The Taste of Total Exertion

An Orientation to the Taste of Total Exertion

Among all the contemplative shifts described in this book, total exertion is perhaps the most difficult to communicate. Unlike insight into the absence of self, which can be approached through careful investigation, total exertion is not first understood conceptually. It arrives as a transformation in the texture of ordinary experience. One does not reason oneself into it; one suddenly finds oneself living within it post anatta.

For this reason, the language in this chapter is necessarily poetic, metaphorical, and phenomenological. No description is intended as a metaphysical claim. Rather, each attempts to point towards a lived immediacy that resists ordinary noun-based language. The reader should therefore approach these descriptions as invitations to recognize a taste rather than propositions to be analysed.

Although total exertion is a single, indivisible realization, it naturally discloses itself through several unmistakable experiential tastes. These tastes are not separate attainments or sequential stages, but different facets of one transformation. They are worth remembering, for each will later become illuminated by Nāgasena’s chariot and finally synchronized through the insight of dependent designation.

The principal tastes are:

  • The universe becomes a single event. Reality is no longer experienced as independently existing things interacting, but as complete participatory events.

  • Intimacy beyond relationship. Separation loses its apparent reality. Participation replaces external connection, not by merging things into one, but because no independently existing boundaries can be found.

  • The end of external conditions. Conditions no longer appear as forces acting upon independently existing entities. They are experienced as the very enactment of the event itself.

  • Dharma-positions and total exertion. Every appearance completely spends itself in being exactly this appearance. Nothing stands behind it, nothing governs it, and nothing remains outside it.

  • Seamlessness without fusion. Boundaries lose their substantiality while distinctions remain perfectly vivid. Diversity is preserved without fragmentation or holism.

  • Dynamic activity without things. Reality ceases to appear as a collection of nouns and reveals itself as living participation. Blowing, burning, flowing, hearing and thinking appear vividly, without nouns behind them, while independently existing things quietly disappear.

  • Luminous immediacy. Experience becomes vividly self-present and unmistakably clear, yet no observer, background awareness, or hidden ground can be found illuminating it. Luminosity is simply the event appearing, not a light added to it.

These tastes should not yet be expected to make complete conceptual sense. Indeed, one of the defining characteristics of total exertion is that the experience matures before the view. The practitioner recognizes these tastes with complete certainty while remaining unable to explain why they are so. This unresolved tension is not a weakness but the very condition that prepares the next great breakthrough. Only later, through Nāgasena’s chariot and the realization of dependent designation, will these seemingly poetic experiences acquire their precise philosophical grammar.

When the Universe Becomes a Single Event

If anatta removes the observer, total exertion reveals the absence of boundaries. This marks one of the most decisive shifts in my contemplative development. While it is not yet the mature realization of the nature of mind/phenomena, it is already a complete departure from ordinary perception, offering the first unmistakable taste of a world organized around immediate relational participation rather than independently existing entities. Unlike philosophical understanding, this realization does not begin as an idea; it begins as a direct taste where nothing is inferred, deduced, or intellectually assembled. Rather, ordinary experience suddenly acquires an entirely different texture. Washing a cup no longer feels like a person handling an object, listening no longer feels like a mind taking in a noise, and speaking no longer feels like words produced by an isolated individual. Every event begins to reveal itself as complete participation.

This taste arises naturally though unexpectedly during ordinary activities, requiring no meditation, special states, or mystical visions. One may simply be walking, hearing the distant sound of traffic, watching leaves move in the wind, or washing dishes when the entire architecture of experience shifts. The activity is no longer something happening to someone, nor is it something being performed by someone; there is only the activity itself, and the whole universe appears to be completely occupied with this one event.

Intimacy Beyond Relationship

Perhaps the primary characteristic of total exertion is an intimacy unlike anything previously known. Ordinarily, intimacy implies that two things have become close, but total exertion operates differently. There are never two independently existing things that subsequently approach one another; there is simply no distance from the very beginning. Hearing is not intimate with sound—hearing is precisely the sounding. Seeing is not intimate with the visible world—seeing is precisely the visible world manifesting as this very event. Breathing is not merely connected to the air; it is the dynamic participation of lungs, atmosphere, body, temperature, pressure, movement, and innumerable conditions functioning together as one immediate occurrence. Nothing bridges these conditions because there was never a gap to begin with. This intimacy is therefore not emotional; it is the absence of any separation existing from its own side.

The End of External Conditions

Ordinarily, language frames 'conditions' as though they surround us—the weather affects us, gravity pulls us, people influence us, and sound and light enter our senses. Total exertion completely overturns this picture. Conditions are no longer external influences acting upon independently existing entities; the conditions are the event. The air does not surround the sound—the air participates as the sounding. The eye does not merely receive light; rather, the eye, the light, the visible form, the nervous system, attention, and countless dependencies mutually enact the seeing. Nothing first exists independently; everything appears simultaneously as relational participation.

The same substantialist habit routinely isolates a quality like coldness from the object of ice, treating the ice as a physical substrate and the coldness as an inherent property belonging to it. In the direct taste of total exertion, however, the coldness of ice does not reside inherently within the ice itself. It involves the temperature of the body, the surrounding air, and the feeling consciousness. None of these components exist in isolation prior to or after the experience. Instead, they are designated together as a single event, none of them prior to the others.

Dōgen's Boat and the Dharma-Position of the Single Thing

No illustration expresses this more precisely than Dōgen's famous description of riding a boat, in the Zenki fascicle of the Shōbōgenzō. One raises the sail and rows, yet the boat carries the rower. Without the boat, no one rides; without the riding, there is no boat as this particular event. The oars, the current, the movement of water, the wood of the vessel, the wind, the body, and the act of rowing are not independent components assembled into a larger system. They are one complete exertion, none of them prior to the event and the event not prior to them.

This should never be interpreted as holism, nor should it be mistaken for a universal substance expressing itself through many forms. Nothing has merged, and nothing has become 'one'. Rather, 'participants' cannot be found prior to the activity itself. The rowing is the rower, the current is the movement, and the boat is the voyage. The event completely spends itself in being exactly this event, which is why Dōgen speaks of total exertion: reality is entirely exhausted in its own manifestation, with nothing remaining behind to direct it.

This completeness of the event can be read alongside Dōgen’s teaching that firewood abides in its own dharma-position, even though it is said to become ash. In the Genjōkōan, this counter-intuitive assertion illuminates the doctrine of dharma-positions (hōji), providing a rigorous framework for the phenomenology of total exertion (zenki). It demonstrates that every discrete appearance is completely whole, structurally severed from linear continuity, and lacking nothing: no wider whole stands behind it to complete it.

The ordinary mind operates under the substantialist illusion that firewood transforms into ash, reifying firewood as the chronological cause and ash as the eventual effect along a continuous temporal axis. Within the immediacy of direct experience, however, this narrative continuity dissolves. Firewood abides in the dharma-position of firewood, fully realized; ash abides in the dharma-position of ash. Each has a before and an after, and yet stands cut off from both—and the positions themselves are designated, not found. Firewood does not actively turn into ash any more than spring inherently turns into summer; each is fully manifested in its own position, with no self-standing reality behind it.

This structural rule applies directly to the reification of human existence, fundamentally altering the conventional anxiety surrounding mortality. When life is present, it is completely alive—a total, uncompromised dharma-position that is not inherently moving towards an external destination called death. Conversely, when death occurs, it is designated as a new dharma-position, distinct from what preceded it. Because these are discontinuous relational moments rather than substantial entities migrating across a timeline, life does not transition into death, just as firewood does not truly transform into ash. It is an ontological error to conceptualize life as merely a prelude to death, or death as an entity following life.

Ultimately, the event spends itself completely in the immediate relational configuration, with nothing held back behind it and no cosmos packed inside it. There is no external, independent timeline by which these fragments are measured or connected. The immediate, functioning event is complete as it is—a dharma-position, conventional and empty, not a locus in which some reality establishes itself.

Seamlessness Without Fusion

The disappearance of the observer gives rise to another characteristic: boundaries lose their solidity, yet distinctions never disappear. This is perhaps one of the most misunderstood aspects of total exertion. The world does not dissolve into an undifferentiated unity; sound never becomes colour, thought never becomes warmth, and fragrance never becomes vision. Difference becomes even more vivid, and every appearance displays its own unmistakable character. At the same time, these differences no longer divide reality into independently existing compartments. Sound does not terminate where silence begins, the body does not end where the environment begins, and the mind does not stand opposite matter. The invisible walls that previously separated phenomena quietly disappear, leaving everything transparent to everything else—not because everything is one substance, but because nothing possesses an independently existing boundary.

Dynamic Activity Without Things

Another unmistakable taste is the transformation of nouns into verbs. Reality no longer resembles a collection of objects; everything appears active and participatory. Wind is no longer a thing that blows—there is only blowing. Fire is no longer an object possessing heat—there is only burning. A river is no longer a noun—there is only flowing. Thinking is no longer produced by a thinker—there is only thinking.

This shift is liberating, yet it also conceals one of the final obstacles. The mind almost inevitably imagines that beneath these verbs there must exist some subtle flowing medium—perhaps awareness, energy, consciousness, or a universal process. The practitioner abandons solid objects only to replace them with a fluid substance, falling into the hidden substrate view. This is a defining characteristic of the transition between Phase Five and Phase Six: the phenomenology is authentic, but the interpretation remains substantialist.

Luminous Clarity Without Background Awareness

There is one further taste that must be made explicit before this chapter closes: luminous clarity. In total exertion, experience is not merely relational, functional, or participatory; it is vividly present. Sound shines as sound, colour radiates as colour, movement reveals itself as movement, and thought appears with its own unmistakable clarity. This luminosity is not a light behind appearances, nor an awareness standing apart to illuminate them. It is the vividness of the event itself.

This point is extremely important. Without it, total exertion may be misunderstood as a merely functional or process-based view of reality. But the taste is far more immediate than that. The world is not only dynamically enacted; it is brightly self-displaying. Every appearance is lucid in its very appearing, yet nothing behind the appearance can be found as its owner, witness, source, or ground. The sound does not need a listener behind it in order to be clear. The visible does not require a background awareness in order to be vivid. The clarity is the manifesting itself, not something it possesses.

The Taste That Cannot Yet Explain Itself

This is why total exertion is so perplexing: it is complete as lived experience, yet its implications remain conceptually unresolved. The practitioner knows with unwavering certainty that the world no longer consists of independently existing things, yet cannot explain why. Questions naturally arise:

  • How can the rower be the rowing?

  • How can nothing stand behind the event?

  • Why doesn't this collapse into holism?

  • How can everything be vividly luminous without a background awareness?

The practitioner therefore inhabits a strange intermediate territory where reality has transformed, but the inherited grammar of thought has not. Experience has become thoroughly non-substantialist, while language continues to speak in the vocabulary of substances, entities, and independently existing things. This is not a failure of practice, but an inevitable stage of maturation.

Indeed, it is this growing tension that becomes the catalyst for the next decisive breakthrough. The taste of total exertion eventually demands its own grammar—a way of understanding that can account for such intimacy without falling back into substance, holism, or nihilism. That grammar is not discovered through further meditative absorption, but through the immediate recognition that Nāgasena's chariot is not merely an ancient analogy about a vehicle. It is a precise description of this very moment of experience. In that instant, the practitioner realizes they have not merely understood the chariot—they have been living as the chariot all along.
