成唯識論述記 7.165

7.165

述曰：下別解也。非所斷者，於五法中唯分別攝。唯有漏故，論決判彼是分別故。《大論》第五說尋、伺決擇四句云：諸尋、伺皆分別，有分別非尋、伺故。今以為證。

The Commentary states: Below is the specific explanation. What is not to be abandoned is subsumed exclusively under conceptualization among the five phenomena. Because they are exclusively contaminated, the treatise decisively determines that they are conceptualization. Fascicle five of the Great Treatise sets forth four alternatives regarding the determination of investigation and analysis, stating: 'All investigation and analysis are conceptualization, but there is conceptualization that is not investigation or analysis.' This is now taken as proof.
