Fire and fuel
Now for something you care aboutThe same argument, with the stakes raised
Session 3 practised on motion, where nobody has anything invested. Chapter 10 turns the identical argument on the one thing every reader does have invested in, and it picks its image with care.
"There must be what is appropriated and one who appropriates it, as there are fire and fuel: fire is the appropriator and fuel is what is appropriated — namely, the five aggregates."
"It is not so. Why? Because neither fire nor fuel is established. Whether fire and fuel are established as one thing or as two, neither way holds."
The technical word is 受 — appropriation, grasping, taking-up. The objector's claim is simple and is what almost everyone believes: there is experience, and there is someone who has it. Body, feelings, perceptions, impulses, awareness are what is taken up; a self is the one taking them.
And the image is well chosen, because fire genuinely does look like a thing that consumes another thing. A flame has a shape, a colour, a behaviour; wood is wood. Two items, one acting on the other.
"Your own word refutes itself"The best objection in the treatise, and it is aimed at the method
Before the argument proper, the objector makes a move that is worth the whole chapter — because it is not about fire at all. It is about whether Nāgārjuna is entitled to speak.
"Set identity and difference aside for a moment. If you say there is no fire and no fuel, how can you then break them by way of the marks of identity and difference? A hare's horn or a tortoise's hair, being nothing at all, cannot be broken. It is only where the world's eyes see that something really is there that one can go on to reflect on it: there must first be gold before it can be smelted and forged."
This is excellent, and every careful reader of the treatise has felt it. You cannot take apart what is not there. Nobody writes a chapter refuting a hare's horn, because there is nothing to refute. The very fact that Nāgārjuna is arguing about fire and fuel concedes that there is something to argue about — and to grant that, the objector says, is to have them already.
The answer is the clearest statement in the treatise of what the whole enterprise takes itself to be doing.
"To speak in accordance with conventional usage incurs no fault. To speak of fire and fuel as one, or as different, is not to accept them. Apart from conventional speech there would be nothing to discuss at all. If one does not speak of fire and fuel, what would there be to break? And if nothing is said, the meaning cannot be made clear."
"A debater who wishes to refute existence and non-existence must speak of existence and non-existence, and he does not accept existence and non-existence merely because he has named them. So there is no blame in speaking as the world speaks. If having a word in one's mouth were already to accept the thing, then your own word "refute" would refute itself."
如有論者欲破有無，必應言有無，不以稱有無故而受有無。是以隨世間言說故無咎。若口有言便是受者，汝言破即為自破，
Naming is not endorsing. The treatise speaks of fire and fuel the way the world speaks of them, because there is no other way to speak, and because without speaking there is nothing to examine. Using a word does not commit you to the metaphysics the word implies.
And then the counter-thrust, which is genuinely funny if you read it slowly: if having a word in one's mouth were already to accept the thing, then your own word "refute" would refute itself. The objector said "you cannot refute what is not there." If speaking of a thing commits you to it, the objector has just committed himself to the existence of a refutation — which is precisely what he was denying could occur.
This is the seed of the two truths, which Session 6 reads in full. Conventional speech is not a concession or a regrettable necessity. It is the only medium in which the ultimate can be pointed at — and the treatise says so here, in passing, four hundred years before anyone made it a doctrine.
One, or differentThe potter and the pot
"If fire is the very fuel,
then act and agent are one;
and if fire is other than fuel,
then there is fire apart from fuel."
若燃是可燃， 作作者則一；
若燃異可燃， 離可燃有燃。
Two horns, and the commentary takes them in turn with an image anyone can check.
"If fire and fuel were one, then act and agent would have to be one too. And if act and agent were one, the potter would be one with the pot. The agent is the potter and the act is the pot; but the potter is not the pot and the pot is not the potter — how could they be one?"
The first horn collapses the distinction the objector needed. If the self simply is the aggregates, then there is no one having the experience — there is only the experience, which is what the objector was trying to avoid. And the aggregates are many and changing, so the self would be many and changing too.
The second horn is where the image does its work:
"If fire were other than fuel, there would have to be a fire found separately, apart from fuel. One could say of this that it is fuel and of that that it is fire, and everywhere apart from fuel there ought to be fire. But in fact it is not so; and so difference will not do either."
Fire is not a substance that arrives and takes up residence in wood. There is no flame waiting in the air for fuel to occupy. Burning is what happens when certain conditions obtain, and to speak of "the fire" as a thing that then consumes "the fuel" is to have taken a process and split it into two items after the fact.
Turn that on the self and the point lands. If the self is genuinely other than body, feeling, perception, impulse and awareness, then it ought to be findable on its own, the way a separate fire would be findable apart from wood. It is not. And a self that can never be found apart from what it is supposed to be appropriating is not related to them as an owner to what is owned.
What the chapter leaves you withAnd where the Yogācārins object
Chapter 10 does not conclude that there is no person. It concludes that the relation between a person and their experience is not the relation of an owner to a possession, because neither term can be established as the kind of self-standing item that relation requires.
What is left is burning. A process, dependent, entirely real as a process, with no separable flame and no separable wood — and also with nobody standing outside it holding a match.
It is worth naming, here, where the other great Mahāyāna school parts company. The Yogācārins accept nearly all of this and then insist on one exception: the dependent process itself is not empty. Something is happening, and that happening has to be real, or there is nothing for the analysis to be about. Nāgārjuna's heirs reply that a "really real dependent process" is one more thing with a nature of its own, smuggled in at the last moment.
Neither school thinks the other is stupid, and the argument ran for centuries. What you can do with this course is see the disagreement clearly rather than pick a side early — which is why the two electives are built to be read together.
- Naming is not endorsing. Conventional speech is the only medium available, and using a word commits you to nothing.
- The self-refutation charge backfires — if speaking of a thing accepts it, the word "refute" refutes itself.
- If self and aggregates are one, there is no one having the experience, and the self is many and changing.
- If they are different, the self should be findable alone, as a separate fire would be findable without wood.
- What is left is burning — a real process with no separable flame, no separable fuel, and nobody outside it.
One practiceLooking for the one who is appropriating
The chapter's claim is checkable in one direction only: you cannot prove the self is not there, but you can look for it where the objector says it must be, and see what you find.
Try the first horn: is it the same as what is happening? If the one having the experience simply is the experience, notice that there is then no one having it — check whether that is in fact how it seems.
Then the second horn: is it separate? Look for it apart from every sound, sensation and thought — apart from all of them at once, not one at a time. If you find something, check whether what you found is itself a sensation or a thought, in which case you have found more fuel and not the fire.
The honest outcome is usually neither of the two horns but a third thing: a strong, persistent sense of a self that cannot be located when looked for. That is not a failure of the exercise. It is the exact situation the chapter describes, and the Yogācāra elective's Session 6 offers a specific account of what is producing that sense.
Check yourselfFive questions
When you say "my experience," what is the relation you take the word "my" to name?
The chapter's claim is that it is not ownership, because neither an owner nor a possession can be established here. What it does not say is that the word is wrong. It says the word works, conventionally, exactly as it has always worked — and that nothing about how it works requires the picture you had behind it.
Session 5 · If nothing has a nature, who acts?
The objection that has followed the treatise since it was written. Take away own-nature and you seem to take away the agent, the deed, and the consequence — and with them the entire moral structure of the tradition. Chapters 8 and 17, on act and agent, and on karma.
