Vasubandhu · Theology
Vasubandhu’s <em>Karmasiddhiprakarana</em> (‘Establishing Action’) faces the hardest puzzle of no-self Buddhism: if there is no enduring self and everything is momentary, how can a deed done now bear its fruit lifetimes later? His answer traces a line of seeds carried in the stream of consciousness.
Buddhism holds two teachings that seem, together, to make its own moral universe impossible. First: there is no enduring self; a person is only a stream of momentary factors, and everything perishes instant by instant. Second: karma is real; a morally weighted deed produces, sometimes lifetimes later, a fitting fruit of pleasure or pain for the one who did it. But put these together and a chasm opens. The deed is long gone - it perished the instant it was done. The doer is gone too, replaced moment by moment, and after death utterly transformed into a new life. So when the fruit finally ripens, what connects it to that vanished deed and that vanished doer? A non-Buddhist can answer easily: a permanent soul carries the moral debt from deed to reward. Vasubandhu has forbidden himself that answer. His short, brilliant treatise the Karmasiddhiprakarana, ‘The Establishment of Action,’ is his attempt to make karma work across the gap that his own metaphysics has torn open - without smuggling a self back in.
Vasubandhu’s key image is agricultural: the seed (bija). A morally significant action does not deposit a lasting token; instead it perfumes or modifies the ongoing stream of consciousness (citta-santana), leaving in it a special potency - a seed - that inclines the stream toward a corresponding future result. This seed is not a little object sitting in storage. It is a real modification of the stream, which flows on, moment conditioning moment, the seed being carried forward and gradually transformed along the way, exactly as a physical seed changes as it develops. When the right conditions arrive, the matured seed yields its fruit: a moment of experience, pleasant or painful, that is the karmic result of the original deed. Nothing unchanging has persisted. What has continued is a causal line - deed, to modified stream, through countless conditioned transformations, to fruit - all of it momentary, all of it flux, yet lawfully connected from end to end.
Vasubandhu’s solution reframes what we even mean by ‘bearing the fruit of one’s deeds.’ It is not that the very same self who acted is later there to be rewarded or punished - there is no such enduring self. It is that the stream which reaps is the lawful continuation of the stream which sowed. The later moments are neither identical with the earlier deed-moments nor unrelated to them; they are their heirs, produced from them through an unbroken causal line, carrying forward the seed the deed deposited. So the maxim ‘you reap what you sow’ is true, but not because a ‘you’ persists; rather, because the sowing and the reaping belong to one continuous, self-conditioning series. This is why karma is neither fatalism (the fruit is not fixed and waiting, but conditioned by all that intervenes) nor injustice (the fruit falls to the very stream that generated its seed, and to no other). Responsibility, like memory, rides on the connectedness of the stream, not on the endurance of a soul.
This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.
You learned that Vasubandhu’s Karmasiddhi asks how an action can bear fruit much later given no-self and momentariness, and answers that the deed ‘perfumes’ the stream of consciousness with a seed (bija) that matures through the stream’s transformations - a solution that eventually pointed toward the storehouse consci…
