The Manas Has Powerful Ability; It Alone Can Accomplish All Dharmas.

Once cultivation has fully developed the power of the manas, and the manas becomes highly capable, it can cast aside its assistants and tools, and without the six consciousnesses and the physical body, it can accomplish all dharmas on its own. For example, in the second dhyāna and above, the five consciousnesses are not needed; in the fourth dhyāna and above, the breathing of the physical body is not needed, nor are the pulse and the beating of the heart to deliver nourishment. In the samādhi of no perception (asaṃjñi-samāpatti), the mind consciousness is not needed; in the heaven of the sphere of nothingness (ākiñcanyāyatana), the physical body is not needed; in the cessation samāpatti (nirodha-samāpatti), only the self and the eighth consciousness suffice. For the great arhat liberated in both ways (ubhayatobhāga-vimukta) and the eighth-ground bodhisattva, the manas alone can know all dharmas, without needing the six consciousnesses.
