楞伽阿跋多羅寶經註解 1.502

1.502

These two analogies specifically say that the eighth-consciousness mind and the six consciousnesses arise in union together, being neither different nor non-different. As for speaking of 'seven consciousnesses', this refers to the mental faculty and the mental consciousness together with the five consciousness groups, and does not mean the seventh consciousness. The sun, moon, and ocean water illustrate the root; the light and waves illustrate the branches.
