大乘起信論裂網疏 2.20

2.20

問：妄念都盡，應是究竟位相，何名分證？答：真見道時，一切分別不現行故，所證真如無分劑故，亦得名都盡也。此後所有增進，並是無漏智品，名為真修。不同有漏聞思修慧，名為緣修，是故不復名妄念也。

Question: If deluded thoughts are entirely exhausted, this should be the mark of the ultimate stage; why is it called "partial realization"? Answer: At the time of the true path of seeing, because all conceptual discriminations do not become active, and because the tathatā realized is without limitation, it may also be said to be "entirely exhausted". All subsequent advancements consist of untainted wisdom factors and are called true cultivation. Unlike the tainted wisdom born of hearing, contemplation, and cultivation, which is called conditioned cultivation, they are therefore no longer called deluded thoughts.
