成唯識論述記 8.473

8.473

述曰：三、染不染門。若言染淨，淨唯善故，亦通無記，故言不染。第十云：於不染中善及無記別，故分二種，通名不染。三唯染，謂無明、愛、取，煩惱性故；七唯不染，謂識等五及生、老死，異熟性故。此約體性而為論也。問：若爾，何故《瑜伽》第十云三染，餘通二種？

The Commentary states: Third, the category of defiled and undefiled. If one speaks of defiled and pure, 'pure' is exclusively wholesome; [but here] it also encompasses the indeterminate, so it says 'undefiled.' Fascicle 10 says: within the undefiled, wholesome and indeterminate are distinct, so it divides them into two kinds, collectively naming them undefiled. Three are exclusively defiled, namely ignorance, craving, and grasping, because their nature is defilement. Seven are exclusively undefiled, namely the five of consciousness, etc., along with birth and aging-and-death, because their nature is true ripening. This is discussed in terms of their essential nature. Question: If so, why does fascicle 10 of the Yogācāra[-bhūmi] say three are defiled and the rest encompass both kinds?
