俱舍論記 29.148

29.148

「此經為顯至如聚如流」者，論主通難。此經為顯能憶宿生一相續身中，假說於我有種種事。若見實我於過去生能有色等，如何非墮起有身見失？然聖知過去非是有身見，作斯徵責。汝或應非撥言無此經。是故此經依總五蘊相續假我言有色等。如聚，緣成假。如流，相續假。無有別體，假立其名。

"This sūtra is meant to show... like a heap, like a stream": the author of the treatise resolves the objection. This sūtra is meant to show that, within a single continuous body capable of remembering past lives, a self is nominally designated as having various states. If one held that a real self in past lives could possess form and so on, how would this not fall into the fault of giving rise to the view of personal identity (satkāyadṛṣṭi)? Yet the Āryas' knowledge of the past is not the view of personal identity—hence this interrogation. Or else, you would have to deny that this sūtra exists. Therefore, this sūtra, relying on the continuity of the five skandhas as a whole, speaks of a nominal self having form and so on. "Like a heap" refers to the nominal designation born of conditions; "like a stream" refers to the nominal designation born of continuity. Having no separate substance, its name is established nominally.
