成唯識論述記 6.169

6.169

述曰：第二師云：五識亦非決定有此，然或有時容皆具有。若上意識增上希望未來境等，即五識無。緣現在境，由意引生，微劣希望亦樂現境，故有欲也。八非意引，任運而生，於境不樂，故無欲也。五識雖無增上審境如第六識，由意引故，亦有微劣印境義也。五識雖無如第六識念曾所受境體之念，亦有意引微劣於現境上念也。現在之境是過去之類，念現在故亦有念也。若第六識亦念過去曾受境體，亦念現在曾受境類，故是增上，皆意引生。

The Commentary states: The second master says: It is not that the five consciousnesses definitively possess these, but rather at times they may possess all of them. If the superior mental consciousness has predominant wishing for a future object or the like, then the five consciousnesses lack it. When apprehending a present object, induced by the mental consciousness, a subtle and weak wishing also delights in the present object; thus they possess desire. The eighth [consciousness] is not induced by the mental consciousness; it arises spontaneously and does not delight in objects, and therefore lacks desire. Although the five consciousnesses do not possess predominant scrutiny of objects as does the sixth consciousness, because they are induced by the mental consciousness, they also possess the subtle and weak function of endorsing objects. Although the five consciousnesses lack mindfulness directed toward the substance of an object previously experienced, as does the sixth consciousness, they also possess, induced by the mental consciousness, subtle and weak mindfulness directed toward present objects. Because present objects are of the same type as past ones, since they are mindful of the present, they also possess mindfulness. As for the sixth consciousness, it is also mindful of the substance of an object previously experienced in the past, and it is also mindful of the type of an object previously experienced in the present; therefore, it is predominant, and all are induced by the mind.
