變有二種：一者生變，即轉變義，如次前說。變謂因果生、熟差別，等流、異熟二因習氣名因能變；所生八識現種種相，是果能變，故能生因說名能變。二、緣名變，即變現義，是果能變。且第八識唯變種子及有根身等，眼等轉識變色等是，此中但言緣故名變，下論言變，准此分別。

Transformation is of two kinds: The first is generative transformation, which is the meaning of modification, as explained just above. 'Transformation' refers to the maturation differences in cause and effect; the vāsanā of the two causes of homogeneous outflow and maturation is called the 'transforming cause' (hetu-pariṇāma); the eight consciousnesses that are generated and manifest various marks are the 'transforming effect' (phala-pariṇāma); hence the generating cause is called the transforming factor. The second is cognitive transformation, which is the meaning of manifesting as an object, and is the transforming effect. The eighth consciousness transforms exclusively into seeds, the body endowed with sense faculties, and so forth; the evolving consciousnesses such as the eye [consciousness] transform into matter and so forth. Here it merely speaks of cognizing as being called transformation; when the treatise discusses transformation below, it should be distinguished accordingly.
