俱舍論記 13.121

13.121

「若起異緣心至憶便止故」者，牒前說一切有部難通釋。汝前難云：若戒無別體，起惡、無記異緣心應無律儀者。此難非理。由受戒者於身、心中念念熏習思種戒力，欲起過時憶便止故。

On "If a mind with a different objective support arises ... because when one remembers, one immediately desists": This cites the previous objection of the Sarvāstivādin to resolve and explain it. Your previous objection stated: if morality has no separate substantial entity, when an unwholesome or indeterminate mind with a different objective support arises, there should be no restraint. This objection is unreasonable. Because the one who received the precepts has the precept-power of the volition-seeds perfumed moment by moment in body and mind, when a transgression is about to arise, upon remembering they immediately desist.
