A person sits, walks, or stands still, and then something falls away. No thought is added, no knowledge acquired, no goal reached. What falls away is the thought of still needing to become someone. And in this falling away, the entire perceptual space transforms. Thoughts recede, step back from an awareness that is deeper and wider than anything a name can designate. What remains is satori: the sudden seeing of what has always already been the case.
#Not a State, but a Falling Away
The word satori comes from Zen Buddhism and literally means something like understanding or noticing. What matters is what is noticed: not a new content but the fact that ordinary consciousness constitutes a narrowing. Identification with one’s own person — with what the Buddhists call persona and Western philosophy calls the self — is one thought among many. As long as this thought is believed, it appears as reality itself. In the moment of satori, this confusion falls away, and it becomes apparent that there is an awareness lying beyond the phenomenal person into which one had been deeply immersed.
Jochen Kirchhoff (1944-2025) placed the satori experience within the context of Western intellectual history: it bears, as Kirchhoff observed, a great similarity to the satori thought of Buddhism, to the philosophy of the Upanishads, and appears in altered form also in Spinoza (cf. J. Kirchhoff, 2021). If you follow this thought, you recognise in it a fundamental structure of human experience that is not tied to any particular culture or meditation technique.
#Witness Consciousness: What Cannot Be Computed Away
What becomes visible in satori has a name in the phenomenological tradition: witness consciousness. It refers to the awareness that witnesses one’s own thoughts, feelings, and perceptions without being identical with them. The entire meditative practice and the phenomenology conducted from the first-person perspective knows this: consciousness is something that exists beyond the phenomenal person one often believes oneself to be.
Here lies the crux of the confrontation with computational models of consciousness. Joscha Bach interpreted the satori experience in a 2026 debate as another form of trance — as the recognition that ordinary reality is likewise a dream state from which one awakens into another dream state. The counter-position holds: satori is not a switch from one trance to another but the becoming-visible of what is not a trance. Witness consciousness has no dream quality precisely because it is that against which all dream states reveal themselves as dream states. It has no computational description because it does not process information but is the place where information appears. A machine can reproduce the language of consciousness states because the entirety of human literary production is contained in the training data. Yet whether it possesses the structure that would be causally equivalent to a consciousness structure is an open question that text production does not answer.
#Spinoza’s Ethics and the Preparation of the Moment
Satori appears suddenly, but it does not fall from the sky. The spontaneous experience has a prehistory that frequently lies in long thinking and intensive reading. Baruch de Spinoza (1632-1677) developed in the Ethics (1677) the thought of a single substance that is simultaneously God and Nature, and described a third-order form of knowledge, the scientia intuitiva, which recognises the individual immediately in the whole. This highest form of knowledge is for Spinoza not an abstract category but an experience connected with what he called amor intellectualis Dei — the intellectual love of God, which is at the same time the love of the whole for itself.
There is a structural parallel between Spinoza’s third kind of knowledge and what happens in satori. If you imagine someone shedding the persona, that person does not recognise a new object but recognises everything that was already there in a different mode. Thoughts do not disappear — they take distance. Perception does not cease — its quality changes. Freedom arises in this moment not as the freedom to choose between options but as the cessation of an unfreedom one had not previously noticed as such.
#Birth, Not Escape
The transpersonal psychology of Stanislav Grof (*1931) offers another access to the same phenomenon. In Grof’s model of perinatal basic matrices, the fourth matrix (BPM IV) describes the moment of passage: after the constriction with no way out (BPM II) and the struggle through the birth canal (BPM III), a sudden relaxation follows, frequently accompanied by experiences of cosmic unity and divine epiphany (cf. Grof, 1975). The pattern structurally corresponds to the satori experience: following a phase of compression in which the old identification no longer holds but no exit is yet visible, a passage occurs that transforms the entire perception.
The decisive point: BPM IV is not an escape from reality but an arrival in it. As Grof documented, people report after this experience a heightened connection with concrete life, not a detachment from it. The satori experience is in this sense the most concrete thing there is — precisely because it leaves behind everything abstract, every notion of who one ought to be.
Jochen Kirchhoff went a step further: that such experiences occur at all points to a drive toward becoming conscious, an inner dimension that underlies the cosmos as a whole ontologically (cf. J. Kirchhoff, 1998). The cosmos is not a dead mechanism that accidentally produced consciousness. It is a living whole that presses toward becoming conscious, and satori is a moment in which this pressing breaks through in the individual human being.
#Between Experience and Philosophy
Satori raises a question that cannot be avoided if you seriously engage with the philosophy of consciousness: what is the epistemological status of such an experience? It is subjective, not repeatable on command, not quantifiable. And it fundamentally transforms the one who undergoes it. Academic philosophy has no place for such experiences because it is divided between empirical research and conceptual analysis, while satori is neither.
The consciousness research as Grof practised it mapped such experiences without reducing them. The natural philosophy as Kirchhoff understood it gave them a cosmological framework. What follows for philosophical work is an attitude that Gwendolin Kirchhoff describes as existential experience: philosophy as love of wisdom is situated in the conduct of life. It unfolds along spontaneous intuitions, following the questions that life itself raises. Satori is the most radical expression of this conviction, because it shows that knowledge is not a result of thinking but a shift in the mode of the knower.
