“The ultimate goal of knowing is to realize that we do not know.” — Chazal

This article explains how the Torah concept of da’as, the power of connective, interpretive knowing, constitutes the most complete and philosophically rigorous account of how human consciousness shapes experienced reality. Drawing on Chazal, the Ramchal, Rav Dessler, the Arizal, and Chassidic teaching, it demonstrates that what modern thinkers have approached through John Boyd’s OODA loop, Peter Ralston’s martial arts philosophy, and the neuroscience of plasticity are partial reflections of an older and deeper truth: the human being is, by divine design, a former of worlds; and the summit of that world-formation is reached not in the accumulation of knowledge, but in the purified openness of knowing one does not know.

I The Paradox at the Summit

There is a sentence in Chazal that, properly understood, reorders everything around it: "The ultimate goal of knowing is to realize that we do not know." It is tempting to read this as a counsel of humility — an instruction that the learned should hold their conclusions loosely, that wisdom begins in an acknowledgment of limitation. But this reading is too thin. Chazal is not issuing a reminder to be modest. It is making a claim about the destination of da'as itself — about where the deepest knowing arrives when it has been followed to its end.

The statement is paradoxical by design. Da'as, in the Torah's understanding, is the highest faculty of the human mind: the power of connective, participatory knowing, through which the human being binds themselves to reality and thereby gives that reality its experienced form. To say that the goal of da'as is to arrive at not-knowing is to say that the highest exercise of this formative power is its own transcendence — that the vessel, when most perfectly formed, becomes most perfectly transparent to what is beyond all form.

This teaching turns out to be the hidden key to a convergence that spans domains as apparently distant as aerial combat theory, martial philosophy, neuroscience, and the mystical teachings of Kabbalah. John Boyd discovered that the decisive variable in conflict was the quality of orientation — the interpretive framework through which a combatant reads an unfolding situation. Peter Ralston concluded that even the finest orientation is a form of interference, and that the deepest responsiveness lies prior to all interpretation. Neuroscience has illuminated how the brain's accumulated structure both enables and constrains perception. And the Torah, long before any of them, had already mapped the entire journey — and, in Chazal's single sentence, had named its destination.

II Da'as: Connection, Not Information

Any engagement with the Torah's teaching on consciousness must begin by correcting a fundamental mistranslation. Da'as is routinely rendered in English as "knowledge," which implies passive cognition — information received, stored, and retrieved. This rendering misses almost everything essential. Da'as, as Chazal and the mekubalim use the term, is the power of connection: the capacity of the mind not merely to receive reality but to bind itself to it, to participate in it, to give it form through the quality of that binding.

This is why the Torah uses the same word for Adam's union with Eve — “v'ha-adam yada et Chava”, "and the man knew Eve" — as it uses for man's highest engagement with G-d. Da'as is not information about something; it is union with something. It is the point at which the inner world of the knower and the reality of the known interpenetrate and, in doing so, shape each other. To know, in the Torah's sense, is to be transformed by what one knows — and to transform, through that knowing, the world subsequently inhabited.

The Ramchal, in Da'as Tevunos, grounds this in the nature of the human being as ‘olam katan’ — a microcosm containing within himself the structural patterns of all creation. Man is not a spectator of a world that exists independently of him. He is, by his constitutive nature, a participant in the ongoing formation of that world. His da'as — his quality of inner connection, orientation, and interpretive engagement — determines which dimension of that world becomes real and present for him. Two people can stand before the same event: one sees divine providence, the other sees randomness; one sees opportunity, the other threat; one inhabits a world alive with meaning, the other a world of mute indifference. The event is the same. The worlds are not.

But Chazal's teaching presses further than even this. If da'as forms the experienced world through its quality of connection, then the question naturally arises: what is the highest quality of that connection? Chazal answers: it is the connection that has become so deep, so complete, so thoroughly freed of the knower's own projections, that it arrives at the recognition of its own insufficiency before the infinite. The goal of knowing is to be brought, by knowing, to the threshold of what cannot be known — and to stand there, openly, without grasping.

III Ralston's "Not Knowing" and Chazal's Crown

Peter Ralston, working entirely within the secular tradition of martial arts philosophy, arrived at what he called the state of "not knowing"— and made it the centerpiece of his system. The resemblance to Chazal's formulation is arresting enough to deserve careful examination, because where the resemblance holds and where it breaks reveals the precise distance between the deepest secular insight and the Torah's account of the same territory.

For Ralston, “not-knowing” is a martial arts and phenomenological achievement. It describes a state in which the practitioner has relinquished the habit of pre-loading a situation with expectation — in which awareness is so fully present to what is actually happening that no interpretive gap exists between perception and response. The practitioner who has reached this state does not decide what to do. Something more immediate than decision operates: perception and action have become, effectively, a single event. The body moves before the mind has completed a thought, not because the mind is bypassed but because its accumulated structure has become so refined and so transparent that it no longer introduces delay between reality and response.

This is a genuine and remarkable achievement. But notice what it is, precisely, that the secular martial practitioner has not known: they have arrived at “not-knowing” as a performance state, a condition of optimal functioning in a domain of physical conflict. The “not-knowing” is instrumental. It is in service of a more effective self.

The Sages are pointing at something structurally similar but categorically different in its orientation. The not-knowing Chazal describes is not the clearing away of mental clutter in order to act more effectively. It is the recognition — reached through the fullest exercise of the knowing faculty — that the reality one is engaging with is infinite, and that the knower, however refined, remains a finite vessel before an inexhaustible source. Ralston's practitioner arrives at “not-knowing” and becomes more effective. Chazal's seeker arrives at “not-knowing” and encounters G-d.

”The ultimate goal of knowing is to realize that we do not know.”

— Chazal

The distance between these two is the distance between a very fast loop and genuine anavah — between a transparent vessel and a vessel that knows itself to be a vessel. One is the peak of human performance. The other is the beginning of encounter with what is beyond the human. And yet they share a structural feature so precise that the comparison illuminates both: in each case, the journey of knowing reaches its summit in the dissolution of the knower's claim to have arrived.

IV Boyd's Orientation and the Arizal's Vessels

John Boyd's great contribution to the theory of conflict was to identify the decisive variable not in strength, speed, or firepower, but in what he called orientation — the interpretive layer through which raw observation is processed before any decision or action can occur. A combatant's orientation is built from the accumulated deposits of training, culture, experience, and ongoing analysis. It is the lens through which the world is read. And because it is a lens, it can distort as readily as it clarifies. Whoever has the more accurate, more flexible, more rapidly updating orientation will, in Boyd's framework, consistently prevail — not because they are physically faster, but because they are living in a more faithful version of what is actually happening.

The Arizal's doctrine of kelim — vessels — is both parallel to this and deeper than it. Divine light, or Ein Sof, is infinite and undifferentiated. What human beings receive of it, how they receive it, and what experiential world is constituted by that reception, depends entirely on the quality of the vessels through which it passes. A vessel formed by humility, trust, and alignment with divine will receives and transmits light in a way that constitutes a world of clarity, providence, and meaning. A vessel deformed by ego, fear, or bitterness receives the same infinite light and constitutes from it a world of concealment, randomness, and threat.

What neuroplasticity contributes to this picture is the biological mechanism by which vessels are formed and reformed. Neural structure is the physical correlate of interpretive habit: the pathways along which perception travels, the patterns into which experience is sorted, the speed and flexibility with which established models can be updated or overridden. High plasticity corresponds, in Torah terms, to a vessel still capable of being shaped — a soul engaged in the ongoing work of refinement. Hardened neural pathways correspond to a vessel that has closed around its current configuration, receiving only what its existing structure allows.

But Chazal's teaching introduces a dimension that neither Boyd nor the neuroscientist possesses the framework to describe. Boyd's ideal is a perfectly adaptive orientation — one that updates so rapidly and flexibly that it approaches real-time fidelity to what is happening. The Arizal's ideal is a vessel so refined that it transmits divine light with minimal distortion. Both are asymptotic projects: improvements along a gradient, approaching a limit. Chazal names that limit: it is not perfect knowledge, not perfect orientation, not perfect plasticity. It is the recognition of “not-knowing” — the moment when the refinement of the knowing faculty has brought the knower to the frontier of what cannot be mapped, and they stand there not in frustration but in a kind of open, wakeful unknowing that is itself the highest form of receptivity.

V Rav Dessler and the Ontology of Worlds

Rav Eliyahu Dessler brings this teaching to its sharpest practical and philosophical edge. In Michtav Me'Eliyahu, he makes a claim that is as radical as anything in modern philosophy of mind, and more carefully grounded than most: every human being lives in a different world. Not in a different psychological experience of the same world. In a different world, genuinely and ontologically distinct.

The four worlds of Kabbalah — Asiyah, Yetzirah, Beriah, Atzilus — are not merely a cosmological schema. They are simultaneously a psychological and ontological map of the strata of reality accessible to human consciousness. A person whose inner life is dominated by ego, reactivity, and self-concern inhabits the world of Asiyah — the densest, most concealed configuration of divine light, where the spiritual dimension of events is maximally hidden and reality presents itself as opaque matter. A person whose inner life is organized by trust, gratitude, humility, and genuine engagement with the divine will inhabits a higher world — one in which the same external events disclose their providential character, in which the same physical reality is experienced as transparent to its Source.

Now consider what Chazal's teaching adds to this map. If the highest goal of da'as is to realize that one does not know, then the world of Atzilus — the highest stratum of experienced reality — is not a world of maximal knowledge. It is a world of maximal openness: a condition in which the knower's vessel has been so refined, and the knower's ego so genuinely relinquished, that the light flowing through them is no longer filtered by the confident assertions of a self that believes it understands. The world of Atzilus is inhabited not by the person who has accumulated the most knowledge, but by the person who has been brought, by genuine da'as, to the most complete and honest not-knowing.

According to the connection that his mind makes with what is above, so will the reality within which he finds himself be created — not merely appear to him that way, but truly be that way for him. Baum

This resolves what might otherwise seem a tension in the teachings of our sages. The same Torah that commands the study and accumulation of Torah and da'as - also, through Chazal, declares that the goal of all that study is to arrive at “not-knowing”. The tension dissolves when one sees that these are not competing claims but a description of a journey. The knowing is real; the disciplines of study, prayer, and character refinement genuinely form the vessel. But the destination of all that formation is not a state of comprehensive understanding. It is a state of refined, purified openness — an unknowing that is not ignorance but its opposite: the condition of a vessel so clear that it can receive what no confident knower can hold.

VI The Baal Shem Tov and the Presence That Precedes Knowing

The Baal Shem Tov's teaching — “b'makom she'machshavto shel adam sham hu nimtza”, "in the place where a person's thought is, there he is entirely" — is not a poetic observation about distraction. It is a metaphysical claim about the nature of human presence. Where your consciousness is oriented, where your da'as is bound, that is the world you actually inhabit — not the world you imagine yourself to be in, but the world you are in, in the deepest ontological sense.

Along Chazal's teaching, this gains a further dimension. If a person is entirely present where their thought is, then a person whose thought is absorbed in their own accumulated knowledge — their maps, their models, their confident interpretations — is entirely present in those constructions. They are, in the most precise sense, living inside their own mind. The world they inhabit is, to a significant degree, a world they have made from the materials of their own past experience. This is exactly what Boyd identifies as the failure mode of a rigid orientation, and exactly what Ralston identifies as the limitation that not-knowing is designed to dissolve.

But for the Baal Shem Tov and for Chazal, the solution is not merely to empty the mind of its constructions, as though pure blankness were the goal. The person whose thought is fully present in emunah — whose consciousness is genuinely oriented toward the divine reality, with all the humility, openness, and not-knowing that genuine emunah entails — is entirely present in that orientation, and the world they inhabit is correspondingly transformed. The Baal Shem Tov's teaching and Chazal's teaching together describe a single movement: away from the world-construction of a self that knows, and toward the world-reception of a vessel that has arrived, through deep knowing, at “not-knowing”.

Ralston's practitioner achieves something structurally analogous: they release the grip of accumulated technique and enter a state of presence so complete that the self, as a deliberating agent standing between perception and action, effectively disappears. The result is peak martial arts performance. The Torah's practitioner, traversing the same structural journey for entirely different reasons, releases the grip of accumulated knowledge and enters a state of presence so complete that the self, as a knowing agent standing between the infinite and the finite, effectively becomes transparent. The result is encounter — not performance, but the condition in which divine reality can be genuinely met.

VII Emunah as the Generative Power of Not-Knowing

It is here that the teaching of the Maggid of Zlotchov, as cited in the Ohev Yisrael, reveals its deepest resonance. The Maggid draws attention to the two roots embedded in the Hebrew word emunah: faith as belief, as intellectual and emotional conviction; and faith as omen — the nurturer, the one who draws forth, sustains, and brings to full development what has been entrusted to their care. True emunah, the Zlotchover Maggid teaches, carries both meanings simultaneously: it does not merely believe that a blessing will come. It draws the blessing down from its heavenly source into manifest reality, acting as a channel through which what exists in potential above becomes actual below.

The connection to the Torah's teaching is now visible in its full depth. What enables emunah to function as this generative conduit? Precisely the not-knowing that genuine faith entails. A person who believes they fully understand how and when a divine blessing will arrive is not exercising emunah — they are exercising prediction. Their vessel is shaped not by openness to the infinite but by confidence in their own model of how the infinite operates. Emunah, by contrast, is the orientation of a person who has been brought, by genuine knowing, to the threshold of “not-knowing” — who trusts without comprehending, who opens without grasping, who receives without insisting on the form of what is received.

The Maggid of Zlotchov, as cited in Ohev Yisrael

The “not-knowing” of the Torah is thus not passivity or emptiness. It is the active, generative condition of a vessel that has been cleared of its own constructions and made receptive to what is genuinely beyond it. The Maggid's teaching reveals that this “not-knowing” has creative power: it draws down. The person who arrives, through disciplined da'as, at genuine “not-knowing” — who stands before G-d without the buffer of their own confident interpretations — becomes the channel through which divine reality flows into the world with the least possible distortion.

Now place this alongside Ralston's account of the practitioner in the state of not-knowing: a person whose awareness is so fully present, so cleared of the compulsive retrieval of stored templates, that action arises without the intervention of deliberation. Both the martial arts practitioner and the person of genuine emunah have traversed a structurally similar path — from conditioned knowing, through the refinement and progressive transparency of the knowing faculty, to an openness that is prior to and more fundamental than any particular piece of knowledge. The destination they arrive at is, structurally, the same kind of place. What that place opens onto is, in each case, entirely different: in one case, the full presence of a physical encounter; in the other, the full presence of the divine.

VIII The Spectrum of Consciousness

In the earlier work from which this article grows, a spectrum of awareness was described in terms of three regions: the constrained mind, stuck in the box of its own conditioning; the adaptive mind, capable of thinking outside the box through high neuroplasticity and flexible orientation; and the unconditioned mind, for which, in Ralston's phrase, there is no box. The Torah's teaching requires that this spectrum be both extended and fundamentally reframed — not because the earlier account was wrong, but because it was missing the dimension that gives the whole structure its meaning.

The constrained mind corresponds, in Torah terms, to the person who lives within the confident projections of their own accumulated past — whose vessel is shaped by fear, ego, and defensive self-certainty, and who therefore inhabits a world of concealment. This person does not merely think they know; their knowing has become a wall between themselves and what is actually present. The adaptive mind corresponds to the serious practitioner of inner refinement — more flexible, more responsive, more capable of updating their orientation when reality insists. Their vessel transmits more light with less distortion, and they inhabit a correspondingly clearer, more expansive world.

Ralston's unconditioned mind — the state of “not-knowing” as a martial arts achievement — corresponds to what the tradition might call the dissolution of the ego's interpretive claim: a condition in which the self no longer inserts its accumulated models between perception and response. This is a genuine and significant attainment, and it opens onto something real. But the Torah points to a further region, which has no secular equivalent and which the secular framework has no resources to describe.

It is the region in which “not-knowing” is not merely the clearing of an obstacle but the arrival at a recognition: the recognition that the reality one is engaging with is infinite, that the self who has been doing the knowing is genuinely finite, and that the deepest act of da'as is to stand at this boundary in full awareness — openly, without grasping, without the consolation of one's own comprehension — and remain there. This is the Torah's “not-knowing”. And it is not the end of the journey but the beginning of genuine encounter.

IX Where the Roads Must Part

The convergences traced in this article are real, and they illuminate each perspective from an angle it cannot provide for itself. There is something genuinely remarkable in the fact that a fighter pilot's analysis of aerial combat, a martial arts’ account of unconditioned awareness, and a neuroscientist's map of cortical plasticity all arrive, by their different routes, at a threshold that the Torah had already named. But the convergences must not be allowed to flatten what is most important about the differences, because those differences are not incidental. They are the boundary between a useful set of insights and the truth those insights partially reflect.

The first divergence is in what “not-knowing” is for. Ralston's “not-knowing” is instrumental: it is in service of a more effective, more responsive self. The not-knowing of the Torah is not in service of the self at all. It is in service of truth — and the truth it serves is specifically the truth of the self's own finitude before the infinite. This is not a subtle distinction. It is the difference between a technique of self-optimization and an act of genuine surrender.

The second divergence is righteous. Neither Boyd nor Ralston has a robust account of why one orientation is better than another in any sense beyond effectiveness. The Torah insists that the quality of da'as is inseparable from the righteous condition of the vessel. Da'as oriented toward ego, even when it produces a superficially clear and responsive orientation, does not generate genuine “not-knowing” — it generates a more sophisticated version of self-assertion. The Ramchal calls the world produced by such orientation a "world of sheker": a constructed reality whose increasing internal coherence only deepens its departure from truth. The Torah's “not-knowing” is only accessible through the genuine refinement of character — through middos, tefillah, and the disciplines of teshuvah. It cannot be achieved by technique alone.

The third divergence is ontological. Boyd and Ralston are describing what a human being can achieve through practice and discipline. The Torah is describing what a human being is by nature and what they are called to become by design. B'tzelem Elokim is not a poetic description of unusual self-awareness. It is a claim about the metaphysical structure of the human soul: that the capacity for world-formation, for the kind of knowing that shapes the reality one inhabits, is not an achievement but a constitutive fact — one that can be developed toward its fullest expression or contracted toward its most distorted, but that is always already present as the defining characteristic of what it means to be human.

X Creation Within Creation, Knowing Within Not-Knowing

G-d alone creates yesh me'ayin — existence from absolute nothingness. This is not a limitation on the human being; it is the ground of the human being's dignity. Because creation from nothing is G-d's alone, what is given to the human being as partner in creation is something different and, in its own way, extraordinary: the power to give form to what exists, to shape — through the quality of da'as, through the refinement of the vessel, through the generative openness of genuine emunah — the world that becomes real, present, and lived.

Every moment of genuine tefillah is a world-formation event: the person's consciousness, aligned with truth and oriented toward the divine, draws down a configuration of reality that would not have been accessible from a less refined inner state. Every act of genuine teshuvah is not merely a righteous correction; it is, as Rav Dessler insists, a movement into a different world — a world in which different things are possible, in which providence operates more visibly, in which the same external circumstances reveal a different dimension of their meaning. And every genuine arrival at “not-knowing” — every moment in which the accumulated claims of the self before the infinite are genuinely relinquished — is a world-opening event: an instance in which the vessel becomes capable of receiving what it could not receive while it was still insisting on its own understanding.

Ralston's practitioner, in the moment of unconditioned “not-knowing”, inhabits a reality that the conditioned practitioner — standing in the same room — cannot access. This is not metaphor. Their range of response, the quality of their presence, the freedom of their movement — these are genuinely different, and they constitute genuinely different realities within a shared physical space. Torah teaches that this same principle operates at every level of the human being's engagement with the world: the person who has been brought, through deep da'as, to genuine “not-knowing” inhabits a world that the person of confident, self-sufficient knowledge, standing beside them in the same room, cannot see — not because it has been hidden, but because the vessel through which they receive reality has not yet been formed to receive it.

The light, as Rav Dessler writes, is one. It does not change. What changes is the vessel. And the most refined vessel, the Torah teaches us, is not the one that knows the most. It is the one that has been brought, by knowing, to the humility of “not-knowing” — the vessel that is open precisely because it no longer insists on its own comprehension, and which therefore receives what no confidence, however well-earned, can hold.

Dedicated to those who marvel at the mystery,
and seek truth in the paradox of opposites.

This appendix examines a body of evidence drawn from extreme sports performance and psycholytic pharmacology — evidence that the nervous system is capable, under certain acute conditions, of temporarily dissolving its habitual interpretive structures and entering a state that functionally resembles what Peter Ralston calls “not-knowing” and what John Boyd's framework describes as the collapse of the OODA loop. The appendix argues that these states constitute genuine and illuminating natural experiments in human consciousness. It argues equally firmly that they remain, in their essence and in their orientation, categorically distinct from the “not-knowing” the Torah places at the summit of da'as — and that understanding that distinction precisely is itself a form of clarity the Torah demands.

I A Phenomenon Worth Examining

It would be easy, from within a Torah framework, to dismiss the reports of rock climbers, BASE jumpers, and surfers who describe peak performance as a state of radical mental silence — a condition in which all learned technique, all conscious deliberation, all sense of a self managing the encounter appears to dissolve, leaving only the clean, immediate fact of movement meeting circumstance. It would be equally easy to dismiss the reports of athletes who have undertaken extreme physical disciplines at psycholytic dosages — doses of psilocybin or LSD calibrated to sharpen rather than overwhelm sensory processing — and who describe not euphoria or hallucination but an uncanny precision of attention, a dissolution of the habitual lag between perception and response, and a quality of environmental presence that ordinary consciousness does not achieve.

These reports deserve neither dismissal nor uncritical embrace. They deserve exactly what serious intellectual inquiry demands of any phenomenon: careful examination of what is actually being described, honest assessment of what mechanisms might account for it, and rigorous discrimination between what it genuinely illuminates and what it is sometimes wrongly claimed to be. In the present context, that means asking a specific and important question: do these extreme states — induced by acute physical danger, by the neurological effects of psycholytic compounds, or by their combination — shed any genuine light on the structure of consciousness that the Torah, is pointing at? And if they do, precisely where does that light end?

II What Extreme Sports Actually Do to the Brain

The neuroscience of high-risk physical performance is by now reasonably well established in its broad outlines. What extreme sports environments do — what separates them from ordinary training in ways that matter for this discussion — is force the nervous system into a mode of operation it rarely sustains voluntarily. The combination of genuine mortal risk, rich and rapidly changing sensory input, and the demand for split-second physical precision creates conditions under which the brain's ordinary operating mode becomes functionally untenable.

That ordinary operating mode is what researchers call the default mode network: the brain's resting-state system of self-referential processing, narrative construction, and predictive modeling. When a person is not actively engaged with an immediate task, the default mode network is highly active — running the internal monologue, rehearsing past events, anticipating future ones, constructing and maintaining the sense of a continuous self moving through time. This network is not pathological. It is essential to planning, memory, and identity. But it is also, in the context of immediate high-stakes physical performance, a source of latency and interference. The narrative self — the self that knows things, has opinions, carries expectations, and comments on experience — is precisely the self that gets in the way when a cliff face demands total present-moment attention.

Extreme sports environments suppress default mode network activity through a combination of acute stress hormones, attentional demand, and the simple biological imperative of survival. The result is what researchers and athletes alike have described as transient hypo frontality: a temporary reduction in the prefrontal cortex's top-down regulatory activity, with a corresponding increase in the immediacy and speed of sensorimotor processing. The gap between perception and response narrows. The sense of a deliberating self standing between stimulus and action recedes. Movement begins to arise, as athletes consistently report, before conscious intention has formed — not because the athlete has ceased to function intelligently, but because the intelligent processing has relocated, becoming faster, more distributed, and less mediated by the narrative overlay of the self-monitoring mind.

In the language developed in the main article, what extreme sports environments produce, at their most acute, is a temporary and involuntary loosening of orientation: the accumulated interpretive framework through which the nervous system ordinarily filters perception is partially suspended, and the practitioner is left operating closer to the raw present moment than habitual consciousness normally permits. Boyd would recognize this as the OODA loop approaching its limit — the stages of orient and decide becoming so compressed as to be functionally invisible. Ralston would recognize it as the spontaneous, situationally-forced version of what his system attempts to cultivate deliberately.

III What Psycholytic Experience Adds

The pharmacological dimension is more contested, and the argument here is correspondingly more carefully scoped. The claim is not about psychedelic experience in general — the high-dose, fully immersive, ego-dissolving states that have been the subject of renewed clinical research in recent years. The specific phenomenon under examination is the psycholytic range: sub-threshold doses at which perceptual and cognitive faculties are altered but not overwhelmed, and at which the practitioner remains capable of skilled physical action, heightened sensory discrimination, and sustained concentration.

At these dosages, the primary neurological mechanism — serotonin 2A receptor agonism — produces a characteristic and well-documented effect: a significant increase in the complexity and flexibility of cortical network activity. The brain's tendency to settle into its habitual, high-confidence processing modes — to perceive the world through the grooves worn by repetition and expectation — is temporarily disrupted. Neural pathways that are ordinarily suppressed by the efficiency-seeking architecture of a trained nervous system become more available. The predictive filtering that normally intercepts sensory data before it reaches conscious awareness is partially lifted. The practitioner, in consequence, receives the world with something closer to fresh contact than habitual recognition ordinarily allows.

Combined with extreme sports environments, this produces a state that several independent lines of evidence describe in convergent terms. Sensory perception is sharpened and enriched. The proprioceptive feedback loop — the continuous information exchange between body and environment — becomes more vivid and more immediate. The sense of the body as a separate object being managed by a mind recedes, replaced by what practitioners describe as a quality of organismic wholeness: the body is not being directed but is simply moving, with an intelligence that feels more distributed and less centralised than ordinary conscious control. And the temporal dimension of experience shifts: the future-orientation of anxious self-management and the past-orientation of technique retrieval both recede, leaving an expanded, more spacious present.

Freeride World Tour Snowboarder

Reports of this kind are common enough across disciplines — surfing, free climbing, wingsuit flight, powder skiing — to constitute a recognizable phenomenological category. What they are describing, in the terms developed in the main article, is a temporary and pharmacologically-assisted suspension of the conditioned interpretive layer: the OODA loop's orientation stage becomes maximally transparent, and the practitioner inhabits something functionally close to Ralston's state of “not-knowing.” They do not, in the moment, know what they will do next. They are not retrieving a template or executing a plan. The appropriate response arises, as Ralston would put it, directly from contact with what is present.

IV Neuroplasticity: The Permanent Effect

The significance of these states extends beyond their duration. A well-established principle of neuroscience holds that acute experiences of heightened plasticity — moments in which the brain's ordinary structural constraints are temporarily loosened — tend to consolidate into lasting changes in neural architecture, particularly when those experiences involve high-stakes skill performance in novel environments. The brain does not simply return to its prior configuration once the acute state has passed. Something has been rearranged.

This is why the combination of psycholytic experience and demanding physical practice is, neurologically, more potent than either alone. The psycholytic state temporarily opens the neural architecture to new patterns of connectivity and response; the extreme environment provides richly demanding content for those new patterns to encode; and the consolidation period following the experience allows what was temporarily accessible to become structurally available. The practitioner, after sustained exposure to this combination, does not merely remember having operated differently. They have, to a measurable degree, become different — their orientation has been updated at a level below voluntary recall, their default perceptual style has shifted, their capacity for present-moment contact has been structurally increased.

In Boyd's framework, this represents an upgrading of orientation: the practitioner's interpretive layer is now more flexible, more rapidly updating, less dominated by habitual templates, and more faithfully calibrated to what is actually present. The loop cycles faster and more accurately not because the practitioner is trying harder but because the underlying neural architecture has been reorganized.

V Where the Illumination Ends

All of the above is genuine, and none of it should be minimized. But the task of this appendix is equally to be precise about what these states are not — and the Torah's teaching makes this precision not merely intellectually desirable but spiritually necessary. The teaching is unambiguous: the ultimate goal of da'as is to realize that we do not know. The “not-knowing” the Torah describes is the destination of the highest human faculty, pursued in its highest direction, arriving at the frontier of the infinite. To confuse this with the not-knowing produced by cortisol, adrenaline, and serotonin agonism in the context of a cliff face is to mistake the shadow cast by a candle for the sun that casts it.

The distinctions are several, and each one matters.

The first is the distinction of direction. The “not-knowing” of extreme sports is, in its fundamental orientation, a “not-knowing” directed inward and outward simultaneously — toward the environment and away from the deliberating self. The practitioner's attention is wholly absorbed in the physical encounter; the self recedes because the demand of the situation has crowded it out. The “not-knowing” of the Torah is directed upward: it is the recognition, arrived at through sustained intellectual and spiritual discipline, that the reality one is engaging with is infinite, and that the human knowing faculty, however refined, is genuinely insufficient before that infinity. One is the self being temporarily displaced by the world. The other is the self being genuinely humbled before what exceeds the world entirely.

The second is the distinction of agency and effort. The “not-knowing” of extreme states is, to a significant degree, involuntary. The nervous system is forced into it by the demands of the environment and the neurological effects of the compounds involved. When the climb ends, the state ends. The practitioner does not carry it as a stable orientation; they return to the default mode, with perhaps a somewhat refined version of their ordinary consciousness. The “not-knowing” the Torah describes is the product of sustained, voluntary, righteously structured effort — decades of Talmud study, of tefillah, of mussar, of the disciplined cultivation of middos. It is not an acute state that passes. It is, when genuinely achieved, a stable orientation of the soul toward a reality that does not change when the climb is over.

The “not-knowing” of extreme states is situationally induced and situationally bounded. It dissolves when the situation changes. It is a temporary loosening of the nervous system's habitual structure, produced by acute environmental and pharmacological pressure.

The “not-knowing” of the Chazal is the destination of a lifetime's directed effort. It is the arrival, through sustained refinement of the knowing faculty, at a recognition that is as stable as any other genuine conviction — the recognition that the reality one stands before is infinite, and that one's own comprehension is, before that infinity, genuinely insufficient.

The first is a neurological event. The second is a spiritual achievement with ontological consequences. The Ramchal is explicit: the quality of one's inner orientation does not merely change how the world appears. It changes the world one actually inhabits. The “not-knowing” of extreme states does not, of itself, open a higher stratum of reality. The “not-knowing” of Chazal does.

The third distinction is the distinction of righteous grounding. The “not-knowing” produced by extreme sports and psycholytic experience is righteously neutral in the sense that it is equally available to persons of any character, any intention, any inner condition. The neurological mechanism does not discriminate. A person of profound ego, using these states instrumentally to enhance performance and personal mastery, will experience something neurologically similar to a person of genuine humility using them as an aid to contemplative practice. The Torah's “not-knowing” is not righteously neutral. It is inseparable from the righteous condition of the vessel. The Ramchal is unequivocal: da'as oriented toward ego — even a da'as that has succeeded in clearing away deliberate interference and achieving a kind of functional transparency — does not arrive at the not-knowing the Torah describes. It arrives at a more sophisticated version of self-assertion. The genuine “not-knowing” of the Torah requires anavah: a humility that is not a mood or a posture but a genuine recognition of one's own smallness before the infinite, earned through sustained encounter with a reality larger than the self.

The fourth distinction is the distinction of what the “not-knowing” opens onto. When a practitioner of extreme sports achieves the state of “not-knowing” — when the deliberating self recedes and action arises in immediate contact with the environment — what they encounter is the richness of the physical world in its most immediate form. The rock, the water, the air, the body: present, vivid, demanding, and entirely without concealment. This is genuine, and it is beautiful. But it is, in the Torah's terms, the world of Asiyah — the physical world — experienced with unusual immediacy and clarity. What the Torah's “not-knowing” opens onto is something categorically different: it is the frontier of the infinite, the threshold at which the human knowing faculty encounters what it cannot contain, and remains there in open, wakeful recognition. The difference is not one of intensity but of ontological level. One is a more complete version of human presence in the physical world. The other is the beginning of genuine encounter with what created the physical world.

VI The Map and What Lies Beyond It

What, then, is the proper relationship between these states and the Torah's account of da'as? The answer suggested by careful analysis is neither "these states are the same thing" nor "these states are irrelevant." It is something more precise: these states are genuinely illuminating natural experiments that demonstrate the reality of a territory the Torah has always described — while being located, themselves, in the outermost precincts of that territory rather than its interior.

The person who has traversed extreme states and genuinely absorbed what they reveal has learned something real: that the deliberating, template-retrieving, narrative-constructing self is not the whole of what they are; that beneath it, or prior to it, there is a mode of intelligent response that does not require deliberation; and that the world, met without the buffer of habitual interpretation, is far richer, more immediate, and more demanding than ordinary consciousness discloses. These are not trivial discoveries. They constitute, in the language of the main article, a genuine movement along the spectrum of awareness — from the constrained mind toward the adaptive and even the unconditioned.

But they do not deliver the Torah's “not-knowing”, and the person who mistakes them for it has made an error with genuine consequences. The error is not merely intellectual. It is the error of believing that a neurological event — however vivid, however transformative, however genuinely illuminating of the structure of consciousness — is equivalent to the recognition arrived at through years of directed, righteously structured, upward-oriented knowing. The Ramchal names this error precisely: the construction of a world that has the appearance of clarity but is oriented, at its foundation, toward the enhancement of the self rather than the genuine encounter with what is beyond it. A more sophisticated, more transparent, more responsive self is still a self. The Torah's “not-knowing” begins precisely where the project of self-improvement ends.

“The ultimate goal of knowing is to realize that we do not know”.

The climber who has dissolved into the rock face has relinquished the deliberating self for the duration of the climb. The person who has genuinely arrived at the Torah's “not-knowing” has relinquished the claim of the self to comprehend — permanently, stably, and not as a performance state but as a form of life. The first is an extraordinary achievement within the human domain. The second is the beginning of something the human domain does not contain.

VII What These States Can and Cannot Do for the Seeker

There is a practical question embedded in this analysis that deserves a direct answer: can exposure to extreme states — the forced transparency of high-risk physical performance, the heightened plasticity of psycholytic experience — serve as a preparation for, or an aid to, the genuine spiritual work the Torah describes? The answer is: possibly, partially, and with important caveats.

The positive case is this. A person who has genuinely experienced the dissolution of the habitual interpretive self — who has felt, even briefly and circumstantially, what it is to respond without deliberation, to be present without narrative overlay, to act from a place prior to the managing mind — has a concrete experiential reference point for what the Torah is pointing at. The abstract teaching that da'as is not information but participation, that the goal of knowing is not accumulation but a kind of open receptivity, that the self's confident interpretations are a veil rather than a window — these teachings can remain purely conceptual for a person who has never felt their own interpretive layer loosen. The person who has felt it, even in a circumstantial and neurological form, has a foothold in the territory the teaching is mapping.

Furthermore, the neuroplasticity that these states genuinely produce is not without value in the context of spiritual growth. A nervous system that is more flexible, more capable of updating its habitual patterns, more receptive to information that does not fit its existing models, is a better instrument for the work of teshuvah and genuine self-examination than one that is rigidly locked into its prior configurations. The Arizal's vessel metaphor is apt here: a vessel that has been somewhat softened, somewhat refined, even by non-spiritual means, is more capable of being shaped by spiritual discipline than one that has never been touched at all.

But the caveats are serious, and they are not peripheral. The first is the caveat of direction. Neuroplasticity produced in the context of self-optimization — in the service of enhanced performance, personal mastery, or the expansion of experiential range — is not automatically available for redirection toward the upward-oriented project of genuine da'as. The neural architecture that has been refined for faster, more transparent physical response has been refined for that purpose. Applying it in the direction of genuine humility before the infinite requires a reorientation that the states themselves do not provide and may, if pursued as ends in themselves, actively impede. The person who has learned to dissolve into flow states on command may find it harder, not easier, to sustain the quality of open, attentive not-knowing that genuine tefillah requires — because they have trained their “not-knowing” to serve the self's performance goals, and that habit is not easily unlearned.

The second caveat is the caveat of righteous condition. The Ramchal's insistence that genuine da'as requires the refinement of middos is not incidental to the system. It reflects a deep structural truth: the quality of the vessel determines what the vessel can receive, and no amount of neurological loosening substitutes for the righteous work of reshaping what the vessel is made of. A highly plastic neural architecture in the service of an unreformed character is simply a more flexible version of the same fundamental orientation. The “not-knowing” it achieves remains, at its root, in the service of the self — and the Torah's “not-knowing” is precisely the recognition that the self is not what deserves to be served.

VIII A Ladder, Not a Destination

The most honest and useful conclusion this appendix can offer is an image: these states — extreme sports performance, psycholytic experience, the neuroplasticity they induce — constitute a ladder. They can carry a person from the constrained mind, stuck in the rigid grooves of habitual orientation, to a genuine experiential encounter with the possibility of something prior to interpretation. They can demonstrate, concretely and viscerally, that the deliberating self is not the whole of consciousness, that action can arise without deliberation, that the world met without the buffer of habitual expectation is a fundamentally different world.

This is not nothing. For many people, in a culture that has systematically identified the self with the deliberating, narrating, planning mind, this encounter is genuinely revelatory. It opens a door that prior experience had kept firmly shut. And the person who has passed through it is, at least potentially, more prepared to hear what the Torah is saying — not as a beautiful abstraction but as a description of an actual territory they have briefly glimpsed.

But a ladder is not a destination. The person who mistakes the ladder for the destination — who takes the peak experience of flow in extreme circumstances as the equivalent of the Torah's “not-knowing” — has stopped at the threshold of something they have not yet entered. They have seen, from outside, the outline of a country whose interior requires a different kind of travel altogether: not the travel of acute neurological states, however genuine, but the slower, less dramatic, righteously structured journey of Torah, avodah, and gemilus chasadim — the journey not of the nervous system being temporarily freed from itself, but of the soul being genuinely, durably, and upwardly reoriented.

The Torah does not say: the ultimate goal of knowledge is to feel like you do not know, briefly, on a cliff face or under the influence of a compound. It says: the ultimate goal of knowledge — the full exercise of the highest human faculty, pursued in its highest direction, over the course of a lifetime — is to realize that we do not know. The word is deliberate. Realization is not experience. It is recognition: stable, clear, integrated, and upward-facing. It is the arrival of the knowing faculty at its own frontier — and the willingness to remain there, open, without grasping, in the presence of what no knowing can contain.
