成唯識論述記 3.101

3.101

問曰：若爾，應離此地，即斷第七，以九品故。答曰：不然，如菩薩十地所斷所知障，一一地通三界所斷，豈無多品。又如菩薩生上，不斷下惑，不障彼者，此例應然，不障有學，雖離此地，故不能斷，要至無學方却斷下。

Question: If so, upon departing from this ground one should immediately sever the seventh [consciousness], because of the nine grades. Answer: That is not so. Just as the cognitive hindrances severed across the ten grounds of a bodhisattva are severed across each and every ground throughout the three realms, how could they not have multiple grades? Furthermore, just as a bodhisattva born into higher [realms] does not sever the lower defilements since they do not obstruct that [higher state], this case should be by analogy the same: not obstructing the [stage of] learning, even though one departs from this ground, it cannot be severed; only upon reaching the [stage of] no-further-learning does one subsequently sever the lower ones.
