成唯識論述記 4.415

4.415

The Commentary states: Where consciousness does not appropriate is precisely non-sentient, of the class of external vessels subsumed under the fruit of leading [karma]. Although the eighth consciousness transforms and also conditions it, it does not appropriate it, like hair, down, and the like; therefore this consciousness exists. Heretofore: first, citing teachings to engage in mutual dispute and separately refuting divergent schools; second, citing empirical facts to pose challenges; third, summarizing the above text.
