成唯識論述記 6.92

6.92

述曰：心等取境已，熏功能在本識中，足為後時有憶念因，何須今念順生後念？或想取像勝故，為因生後時念足得；何待今念，後念方生？

The Commentary states: When the mind, etc., have grasped an intentional object, their perfumed capacity residing in the fundamental consciousness is sufficient to serve as the cause for having recollection at a later time; why would present mindfulness be required to directly produce subsequent mindfulness? Alternatively, because saṃjñā is superior in grasping images, it is fully sufficient as a cause to produce subsequent mindfulness; why wait for present mindfulness for subsequent mindfulness to arise?
