成唯識論演祕 4.463

4.463

有義：如等流五識所緣現境，雖非曾受而是率爾五識所得境之種類，名曾受境。五識既爾，意識准知。此之後心，緣前類境，亦得念起。今第七識唯緣類故，故說有念。所執賴耶是無始時曾受類故，緣現境故非緣曾受。

One opinion holds: Just as the present objects apprehended by the homogeneous five consciousnesses, though not previously experienced, are kinds of objects acquired by the immediate five consciousnesses, they are called previously experienced objects. As this is true of the five consciousnesses, the mental consciousness should be understood by analogy. A subsequent thought of this, apprehending an object of the prior kind, can also give rise to mindfulness. Now, the seventh consciousness only takes kinds [of objects] as its object, so it is said to have mindfulness. The grasped ālaya is a kind previously experienced since beginningless time; because it takes a present object as its object, it does not apprehend the previously experienced.
