成唯識論述記 7.487

7.487

The Commentary states: This is from the Ghanavyūha-sūtra: 'The objects of cognition of citta, manas, and vijñāna do not depart from their own nature'—that is, taking the substance of consciousness, or its phenomenal nature, which is one's own mental dharma, or its real substance, which is the original entity that forms the basis of the object. This means that the objects of cognition of the eighth mind, the seventh manas, and the remaining six consciousnesses all take one's own mind as their object. The Buddha stated: by virtue of such reasoning, I say that all conditioned and unconditioned dharmas are vijñapti-mātra, and there is no other real object external to the mind.
