成唯識論述記 3.46

3.46

述曰：雖識所變假名種子，非實種子，現行法故。《攝大乘》云：「作、不作、失、得過，故成相違，外種內為緣，由依彼熏習」，又引頌云：「天地風虛空，波池方大海，皆真內所作，分別不在外」，故由內種，外穀等熟，彼非實種。問：種亦識所變，應非實種子？答曰：不然，內種識變已，復生麥等，麥等復識變，以重變故，故非種子，如眼根等。故下文云：「外麥等剋體，非因緣生果」，故因緣唯內種，非外種故，此等已上並《攝論》有。

The Commentary states: Although they are transformed by consciousness and conventionally called seeds, they are not real seeds, because they are actualized phenomena. The Mahāyānasaṃgraha states: 'Because of the faults of action, non-action, loss, and gain, there is contradiction; external seeds have the internal as their condition, arising through dependence on that perfuming.' It also cites a verse: 'Earth, sky, wind, space, / waves, ponds, directions, and the great ocean / are all truly made by the internal; / conceptual discrimination is not external.' Thus, it is due to internal seeds that external grain and so forth ripen; they are not real seeds. Question: Seeds are also transformed by consciousness; should they then not be real seeds? Answer: This is not so. After internal seeds are transformed by consciousness, they further produce barley and so forth, and barley and so forth are again transformed by consciousness; because they are doubly transformed, they are not seeds, just like the eye faculty and the like. Therefore the text below states: 'External barley and the like, in their definite substance, do not produce fruits through primary causes.' Thus primary causes are only internal seeds and not external seeds; all these points above are found in the Mahāyānasaṃgraha.
