Nothing arises, in four ways
The verse that is the methodFour corners, and the door shut on each
Session 1 was the statement of position. Here is the first argument — and it is worth reading slowly, because every subsequent chapter is this same move applied to a new subject.
"Things do not arise from themselves,
nor do they arise from another,
not from both, nor without a cause —
therefore we know there is no arising."
諸法不自生， 亦不從他生，
不共不無因， 是故知無生。
Four possibilities, and they are genuinely exhaustive. If a thing comes into being, it does so from itself, from something else, from both, or from nothing. There is no fifth option — and the verse does not argue against a particular theory of causation but against the whole space of them.
Notice also what the verse does not say. It does not say things do not appear. It says the arising — the findable event of coming-to-be, with a nature of its own — cannot be located in any of the four places it could be.
Corner by cornerPiṅgala's commentary, doing the actual work
The first corner falls to an argument that is easy to state and hard to escape.
""Not from themselves": nothing among the ten thousand things arises out of its own substance; each must wait upon a host of causes. Furthermore, if a thing arose from its own substance, then one thing would have two substances — one that is the arising, and one that is the thing doing the arising."
Two objections, and the second is the sharper one. Self-arising requires the thing to already be there in order to do the arising — which means it did not need arising. And it splits the thing in two: the one that does the producing and the one that gets produced. A single thing with two substances is not a single thing.
The second corner — arising from another — looks much more plausible, and is how almost everyone actually thinks. The seed produces the sprout; they are different things. The commentary's reply is very short and very strong:
"And since there is no "self" here, there is no "other" either. Why? Because it is only on the basis of a self that there is anything to call another."
This is the treatise's characteristic move, and once you see it you will see it in every chapter. Other is not a property a thing has on its own. It is a relation — a thing is other than something. If nothing has a self-standing nature, then nothing has the standing required to be the "other" in that relation either. The first corner having fallen, the second falls with it, because it was leaning on the first.
The third corner is arising from both, and it needs no separate treatment: it carries the faults of the first and second at once. Two broken accounts do not repair each other.
Which leaves the fourth — arising without any cause. Here the commentary does something a modern reader may not expect from a book with this reputation. It refuses the position on moral grounds:
"Without a cause there is no fruit; and if fruit could come without a cause, then giving and keeping the precepts ought to land a person in hell, and the ten evil deeds and the five heinous crimes ought to get a person born in heaven — since there would be no cause involved either way."
Uncaused arising is not merely unlikely; it makes the connection between what you do and what follows arbitrary, and with it every distinction the tradition rests on. Notice that the treatise is here defending causation, against the position that things simply happen. This will matter in Session 6, when it is accused of destroying exactly what it is here protecting.
The four conditions, and the fruit that is nowhereTaking apart the Abhidharma's own machinery
Now the objector plays the strongest card available inside Buddhism. Never mind the philosophers — the Abhidharma, the tradition's own technical analysis, has a worked-out theory of causation. Four conditions, and everything is produced by them.
"The Abhidharma masters say that things arise from four conditions. How can you say there is no arising? And what are the four conditions?"
"The causal condition, the antecedent condition,
the object condition, the dominant condition:
these four conditions produce all things,
and there is no fifth condition."
因緣次第緣， 緣緣增上緣，
四緣生諸法， 更無第五緣。
It is worth registering what has just happened. That verse is not Nāgārjuna's objection; it is the Abhidharma's own doctrine, stated accurately and in full, in the treatise's own verses. He states the opposing position better than the opponent would, and only then takes it apart.
And the taking-apart turns on a single question: where is the fruit?
"In the conditions, taken together or singly,
no fruit can be found by searching;
and if it is not in the conditions,
how could it come out of them?"
略廣因緣中， 求果不可得；
因緣中若無， 云何從緣出？
The dilemma is clean. If the sprout is already in the seed, nothing is produced — it was there. If it is not in the seed, then something is coming out of a place where it was not, and the seed is doing no explanatory work at all: anything could come from anything.
And the commentary closes both halves of the search: "Taken together" means: there is no fruit in the conditions assembled. "Taken singly" means: there is no fruit in any one condition either. You cannot find it in the parts, and you cannot find it in the assembly of the parts.
What is leftThe point where most readers go wrong
Stop here and take stock, because this is the moment at which the misreading Session 1 warned about becomes irresistible. Arising has been refuted in four ways; causation's own machinery has been shown to have no place where the effect is. It looks as though nothing causes anything.
That is precisely the conclusion the treatise was written to prevent — remember that it exists for people who heard emptiness and thought it cancelled morality.
The distinction is everything. The seed-and-sprout process continues exactly as before and is entirely reliable. What cannot be found, under analysis, is a discrete self-standing event of production — a moment at which a thing with its own nature is manufactured out of another thing with its own nature.
Nāgārjuna's positive claim, when he finally makes it in Chapter 24, is that this is what dependent arising has meant all along: things depend, therefore they have no nature of their own, and having no nature of their own is exactly what makes it possible for them to depend. Emptiness is not the opposite of causation. It is its condition.
Session 6 reads that argument in full. What the intervening sessions do is apply the method of this chapter to the things people are least willing to let go of — motion, the self, karma, and finally the Buddha and nirvāṇa themselves.
- Four corners, and they are exhaustive. From itself, from another, from both, from nothing.
- Self-arising splits the thing in two — a producer and a produced — and requires it to exist before it exists.
- "Other" is a relation, not a property. The second corner falls because it was leaning on the first.
- Uncauased arising is refused on moral grounds: it would make merit and murder equivalent.
- The opposing doctrine is stated accurately first, in the treatise's own verses, before it is examined.
- The fruit is in neither the parts nor the assembly. Either it is already there, or it comes from where it was not.
One practiceLooking for the moment of production
The fruit argument is not abstract, and it does not require you to accept anything. It requires you to look for something and report honestly whether you found it.
Look for the boundary. Before it, no fruit; after it, fruit. Try to place it. When you think you have, ask whether at that instant the effect is already present (in which case it was not produced then) or still absent (in which case it was not produced then either).
Then notice what you actually observed: a continuous change, fully reliable, with no findable instant of manufacture in it.
Two things this cannot show. It cannot show that no such moment exists — only that it is not observable, which is a weaker claim. And it must not be taken to mean the water does not heat. If the exercise leaves you doubting that causes work, you have drawn the conclusion this chapter was written to prevent.
Check yourselfFive questions
If you cannot find the moment at which anything is produced, what exactly have you been relying on all your life?
The treatise's answer is: dependence, which is entirely reliable and has never required a findable act of production to work. What you were relying on was never in danger. What is in danger is a picture of it.
Session 3 · The walker and the walked
The most famous demolition in the treatise, and the one that most infuriates first-time readers. Somebody is walking to the market. Nāgārjuna asks where the going is — in the road already walked, the road not yet walked, or the walking now — and does not let go for ninety exchanges.
