成唯識論述記 4.27

4.27

The Commentary states: Because it appropriates the five corporeal faculties, the five consciousnesses can operate. That is, it shows that this consciousness serves as support indirectly. If it did not hold the five faculties, consciousness would not be able to rely on them, like a corpse and so forth. Therefore it is spoken of as a condition; it also has a seed-support. However, that is a cause-condition; now it is discussed in terms of the predominant condition of the five faculties, which is mutually accepted, as an evident matter. Next, it explains the "mental consciousness."
