Chapter 2: Nibbāna, the fire and tree similes, and phenomenology¶

The simile left at the scene of the teacher's death is a lamp. When the Buddha attained parinibbāna, Anuruddha spoke a verse: the liberation of the mind was like the going out of a lamp.¹ Earlier, the nun Paṭācārā had used the same image at the moment of her own attainment. Pressing down the wick with a needle, she said: as the lamp went out, my mind was liberated.² One scene is a death, the other an awakening in this life. Two moments share one lamp. This detail is our point of entry. If the lamp's going out stood for death, it should not appear in a living person's verse of attainment. It works in both places only because what is extinguished is always the fire, never the person. Chapter 1 has already identified which fire: greed, hatred, and delusion. The Fire Sermon, preached to fire worshippers, makes this explicit. Everything is burning: the eye, visible forms, eye-consciousness, eye-contact, and feeling all burn with the fires of greed, hatred, and delusion.³ The word nibbāna itself belongs to the vocabulary of fire: the fire going out. The name presupposes fire, and from the outset the texts identify that fire with the defilements.

The two sides of the similes. To read fire, lamps, and trees merely as rhetoric of extinction is to miss half their work, and the crucial half at that. The fire simile is first a model of continuity. Fire is named after its fuel: burning wood, it is a wood fire; burning grass, a grass fire. Consciousness is likewise named eye-consciousness when it arises dependent on the eye and visible forms, ear-consciousness when it arises dependent on the ear and sounds. This is how the Buddha corrects the monk Sāti, who maintains that the same consciousness travels through the destinations of rebirth. The Buddha refutes him: consciousness arises dependently; apart from conditions, there is no consciousness. Here the fire simile concerns not extinction but the absence of a core in consciousness.⁴ The Discourse on the Debating Hall goes further, applying the fire simile to continuity at a point of suspension. When a flame is blown away from one piece of fuel but has not yet reached another, what sustains it? Wind sustains it. When a being has left this body but has not yet taken another, what sustains it? Craving sustains it.⁵ Between two pieces of fuel, the flame does not touch ground; its sustaining support forms the bridge. The lamp simile likewise has a side concerned with continued burning: someone keeps adding oil and tending the wick, and the lamp burns brightly for a long time. The tree simile has an entire conditional vocabulary of cultivation: clear the ground around the roots, heap up soil, and water it. With this care, a sapling grows, increases, and expands.⁶ Ignition, too, has its conditional vocabulary: wet wood immersed in water cannot produce fire; wet wood on the bank cannot produce fire either; only dry wood away from water can do so.⁷ One set of images spans ignition, maintenance, transmission, and extinction. This is no rhetorical coincidence. It shows that the tradition possessed a complete vocabulary of process: arising, persisting, continuing, and ending, with a simile for every term.

Five principles. The philosophical position carried by this vocabulary can be gathered into five statements.

First, phenomena have no underlying ground. Roots appear everywhere in the similes, but a root is a condition, not a substrate. Cutting roots means cutting off supply, not digging up an underlying substance. The canopy flourishes because roots, soil, and water continually supply it; flourishing is not a property of the tree. While the supply continues, the canopy remains; when the supply is cut off, the canopy is no more.

Second, continuity of phenomena requires no core. Flame passes from fuel to fuel, crossing by way of wind. Continuity is maintained by sustaining support, not by something handed across. Sāti's view of the same consciousness traveling through rebirth is rejected at precisely this point: continuity is real; a continuing bearer is fictitious.

Third, phenomena exist when all their conditions are in place. Oil and wick sustain a lamp's flame; roots, soil, and water sustain a canopy; fuel and wind sustain fire. "Existence" is a borrowed word here. What the similes give us is only occurrence: fire burns, a tree grows. When conditions gather, the event appears; when conditions disperse, it ceases.

Fourth, when the required conditions are temporarily lacking, a phenomenon temporarily fails to arise. The texts have ready similes for this case. An intact seed without soil or water does not grow, but it is not dead; once soil and water arrive, it grows.⁸ The attainment of cessation is an experiment in suspension that the tradition conducted for itself. In this attainment, feeling and perception both cease. How does the meditator differ from someone dead? Life is not exhausted, warmth has not dissipated, and the faculties remain clear. The conditions have not been withdrawn, so cessation can be followed by return.⁹ Wet wood cannot produce fire today, but it can once it dries. Temporary interruption also has a close neighbor that must be distinguished from it: Rāhu eclipsing the sun or moon, or clouds and mist covering their light, is concealment, not interruption. A covered lamp and an extinguished lamp are two different things.¹⁰

Fifth, when conditions are wholly removed, the phenomenon does not arise again. The group of discourses on the great tree presents this as an engineering procedure: cut the roots, dig them out, remove every rootlet, chop into sections, split them, shave them into chips, expose them to wind and sun, burn them to ash, and scatter the ash in a strong wind or sink it in running water. In the future, the tree becomes incapable of arising.⁶ A palmyra palm whose crown bud has been cut off never revives; a scorched seed never sprouts again; when oil and wick are exhausted, the lamp's flame goes out by itself. The fifth principle's painstaking account of these procedures is deliberate: it distinguishes total removal of conditions from a single cut. Fell a tree without damaging its roots, and it grows again; fail to uproot the latent tendency to craving, and suffering returns.¹¹

The correspondences between the five principles and the three families of similes can be surveyed in one table:

With and without remainder. We can now work through the distinction left open in Chapter 1. The Itivuttaka explicitly distinguishes two nibbāna elements. In nibbāna with a remainder of the basis, the fires of greed, hatred, and delusion have gone out in this life, but life remains, the five faculties remain, and pleasure and pain are still experienced. In nibbāna without a remainder of the basis, after this life ends, all feeling, no longer delighted in or craved, will become cool right here.¹² Returned to the simile, the period with remainder is a lamp to which no more oil is added. The flame still burns, but only the remaining oil is burning; the hand that added oil has withdrawn, while the oil is not yet exhausted and the flame has not yet gone out. The two-sided lamp simile in the Discourse on Fetters fits this exactly: keep adding oil and tending the wick, and the lamp burns brightly for a long time; add nothing and tend nothing, and once the previous oil and wick are consumed, it goes out for lack of sustenance.¹³ The Discourse on the Sick Ward and the Discourse on the Analysis of Elements entrust the moment of death to the same process word: at the breakup of the body, at death, all that is felt, not delighted in or craved, will become cool right here.¹⁴ In the Vappa Sutta, the tree and cooling meet in one place. A shadow depends on a stump; dig out the roots and burn them to ash, and the shadow no longer appears. The same discourse uses the same formula: at the breakup of the body, at death, it will become cool right here.¹⁵ Watch the grammatical character of these expressions: cooling, ceasing, and no longer appearing are all process words. The texts never grant the arahant a new state conceived as an entity during the period with remainder, nor specify a destination after the remainder is gone. Chapter 1 asked whether nibbāna with remainder is cessation as an event or a state of existence that can be posited. The similes lean toward the former. Their reason is that only processes and their conditions can be posited: fire and fuel, flame and oil, canopy and roots. Once a process ends, this vocabulary has no reserved entity column for the process that has ended.

As for nibbāna without remainder, what the similes do at the boundary has the same structure as the rejection of all four alternatives in Chapter 1. Once a fire is out, it makes no sense to ask whether it went east, west, north, or south.¹⁶ Sparks struck on an anvil gradually cool and die out, their destination unknowable.¹⁷ Once a shadow ceases, we do not ask where it has returned. The similes do not declare that it has nowhere to go: that is the form of an annihilationist view. They merely deprive the question of destination of its footing. Chapter 1 said that nibbāna without remainder can have no positive relation to worldly phenomena: predication cannot find a hook. The similes make that claim tangible. The hooks were attached to fuel, oil, and roots all along. When fuel, oil, and roots are exhausted, the hooks hang in the air.

A phenomenological approach, and its restraint. We can now make good on the chapter's title. All three families of similes describe processes: ignition, maintenance, transmission, exhaustion, cessation. None describes where an entity goes. There is affirmative vocabulary: cool, secure, smokeless, cooled. But these words name the experiential side of cessation, not a table of attributes of the farther shore. To call someone cool is to say that the three fires can no longer burn in that person, not to report the temperature of some realm. This vocabulary is complete within phenomena: each of the five principles can be stated, and each has a simile. Its restraint consists in stopping after the fifth, without adding a sixth. Chapter 1 left a question open: does rejecting all four alternatives mark a limit of logic, or of predication and conceptualization? The phenomenology of the similes gives this book grounds for a judgment: it is the latter. The four alternatives are logically exhaustive; what fails is not their arrangement but the conditions of their application. Before predication can work, there must be a relation within worldly phenomena to which it can attach. The vocabulary of process runs out where the process ends. To write another sentence would require a vocabulary of entities. Yet once the plantain trunk has been stripped of every layer, that vocabulary is no longer authorized. The limit arises at language's working surface, not within logic itself.

Precisely for this reason, later interpreters can each take what they need from the same stock of similes. In Vedic fire physics, a fire's going out is not its destruction but its return to a latent, diffused condition; the extinguished-fire simile can thus be read as release.¹⁸ A reading through the history of polemic takes the preaching of extinction to fire worshippers as itself a subversion of the sacrificial-fire tradition.¹⁹ A reading through conceptual history takes nibbāna as the full stop of a narrative: a full stop describes nothing; it simply lets narration come to a fitting end.²⁰ These three readings compete for the same empty place. The simile stops where the process ends and refuses to continue. Anyone who wishes to continue must bring their own metaphysics. This demonstrates the similes' restraint from the other side.

The question of the fuel. One inevitable further question must still be closed off: if fire is not underlying substance, is the fuel? This kind of phenomenology inevitably invites a second question, which moves the entity back from phenomenon to substrate. The texts address it in four layers. First, the fuel too is burning. In the Fire Sermon, what burns is not just fire: eye, visible form, consciousness, contact, and feeling all burn. The fuel is itself process, not a pedestal beneath process. Second, the plantain simile: form is like a lump of foam, feeling like a water bubble, perception like a mirage, formations like a plantain trunk, and consciousness like a magical illusion. Peel the plantain layer by layer, and there is nothing solid within. The layer taken as a substrate proves, on inspection, equally without a core.²¹ Third comes the formulation about dependently arisen phenomena. Dependent arising is a law that always holds, but its links are themselves dependently arisen: impermanent, conditioned, arisen through conditions. Conditions themselves have conditions. Asking after the fuel yields only a cascade, never a foundation.²² Fourth, the chariot simile: when parts gather, the world calls it a chariot; when aggregates gather, the world calls it a being. Parts have no better claim than wholes to be underlying substance.²³ Together these four layers say one thing: the similes leave no layer of substrate to which one can retreat. The Discourse on the Burden seems to invite the bearer back in: burden, taking up the burden, laying it down, and bearer. Later Pudgalavādins cite it as scriptural evidence. That is the topic of Part I, Essay 3, Chapters 5 and 6; a signpost suffices here.²⁴ Pursued downward, the question of the fuel leads to the four great elements. In the Discourse on the Analysis of Elements, earth, water, fire, and air each receive the same injunction: they are not to be appropriated as self or mine. This belongs to Chapter 3. Pursued forward, fire and fuel are dismantled together in the chapter on fire and fuel in the Mūlamadhyamakakārikā. That belongs to Essay 18.²⁵

Return to the lamp. Anuruddha's verse does not say where the revered teacher went, only that the liberation of the mind was like a lamp's going out. At its moment of deepest grief, the tradition chose similes from ordinary household things: a hearth, an oil lamp, trees, seeds. Processes are visible every day; so is their cessation. The vocabulary of nibbāna was not fashioned into an exclusively sacred image, and that fact itself forms part of the restraint. How much of this restraint later held, and through which gaps leakage occurred, are questions for Chapter 7; we set them aside here.
