大乘義章 12.19

12.19

次就三善分別五度。言三善者，所謂無貪、無嗔、無癡三善根也。五度觀中，不淨觀門是無貪性，慈悲觀門是無嗔性，餘三觀門是無癡性。若論眷屬，即五陰性，定共無作是即色陰，受數為受，想數為想，心王為識，餘為行陰（此三門竟）。

Next, the five gates of deliverance are differentiated in terms of the three roots of good. The "three roots of good" refers to the three good roots of non-greed, non-hatred, and non-delusion. Among the contemplations of the five gates of deliverance, the gate of the contemplation of impurity is of the nature of non-greed; the gate of the contemplation of kindness and compassion is of the nature of non-hatred; and the remaining three gates of contemplation are of the nature of non-delusion. If discussed in terms of their retinues, they are of the nature of the five aggregates: the unmanifest [matter] concurrent with samādhi is the form aggregate; the caitta of sensation is sensation; the caitta of conception is conception; the primary mind is consciousness; and the remainder are the aggregate of formations. (This concludes the third gate.)
