唯識三十論要釋 1.7

1.7

由假說我法　有種種相轉
彼依識所變　此能變唯三
謂異熟思量　及了別境識

Due to metaphor, ātman and dharmas are spoken of, / and various aspects arise.
They depend on the transformation of consciousness; / these transformations are only three:
namely, maturation (vipāka), cogitation (manana), / and the consciousness of perceiving objects (viṣaya-vijñapti).
