成唯識論述記 6.173

6.173

述曰：五識雖無推度深取，亦有微劣簡擇之義，故有惠俱。由此《大論》六十六說：眼、耳二通是二識相應智。前師解此，如前已說。既二識有惠故，例餘三識亦然。或是無記，或生得惠，或加行惠，聞、思修所成即彼類故。《佛地論》說除漏盡、神通，餘通妙觀察智者，以眼、耳俱意，亦是二通故，多時相續不間斷故，五識數間斷故。但說意俱之者，多分妙觀察智攝。

The Commentary states: Although the five consciousnesses lack deep apprehension through inference, they also possess a subtle and weak discernment; therefore they are accompanied by discernment. Hence, the sixty-sixth fascicle of the Great Treatise states that the two superknowledges of the divine eye and divine ear are wisdom associated with those two consciousnesses. The former master's explanation of this was as stated before. Since these two consciousnesses possess discernment, by analogy the remaining three consciousnesses do so as well. It is either morally indeterminate, innate discernment, or discernment acquired through effort, because that which is accomplished through listening, reflection, and cultivation belongs to that category. When the Buddhabhūmi-śāstra states that, setting aside the knowledge of the exhaustion of taints and [other] superknowledges, the remaining superknowledges are subsumed under the wondrously observing wisdom, this is because the mental consciousness co-arising with the eye and ear also constitutes the two superknowledges, and because it continues for a long time without interruption, whereas the five consciousnesses are frequently interrupted. Thus, it says that those co-arising with mental consciousness are for the most part subsumed under the wondrously observing wisdom.
