大乘百法明門論疏 1.75

1.75

"Fourth, regarding the distinction of the layers: the five consciousnesses such as the cakṣur-vijñāna and the manas have three layers: namely, seeds are the first layer, active manifestation is the second layer, and being cognized by the sixth mano-vijñāna is the third layer. The sixth mano-vijñāna has three layers: seeds are the first layer, active manifestation is the second layer, and earlier and later cognizing each other is the third layer. The ālaya-vijñāna has four layers: namely, seeds are the first layer, active manifestation is the second layer, being cognized by the sixth mano-vijñāna is the third layer, and being cognized by the manas is the fourth layer.
