成唯識論演祕 2.404

2.404

Answer: There are two explanations. One says it is single in substance, like the life-faculty; the other says it is multiple in substance, like the dharmas upon which it relies. The latter explanation has support, whereas the former has no textual authority. Hence the Nyāyānusāra says: 'What is fruition? It refers to the generic similarity of destinies, births, and so forth. What is concordant flow? It refers to lineage, etc.' Furthermore, what is induced by prior karma is fruition; what is produced by present application is concordant flow. If it were like the life-faculty, it would be solely fruition; how could there be concordant flow? The generic similarity of dharmas also has two explanations, which can be understood by analogy with the preceding.
