成唯識論述記 2.724

2.724

述曰：前因能變中言，異熟習氣既是種子，未知生何？如何生果？能起何果？今顯增上緣生，不親生故，所生真異熟者，唯第八識，增上緣生性不同故，唯第八識是總果故，是果之主，餘果方生，主引生故，由強勝業引總果故，餘別弱業方能生果。據其勝業名引，引餘業生故；報亦名引，引餘果故；業勝名引，果無間故，說恒相續，由恒相續，及是引果立果熟名，餘法亦爾。

The Commentary states: In the discussion of causal transformation above, it was said: since maturation latencies are seeds, one does not yet know what they produce. How do they produce fruits? What fruits are they able to give rise to? Now it is shown that they are produced by decisive condition and do not produce directly. That which is produced as true maturation is only the eighth consciousness. Because things produced by decisive condition are not of the same nature, and only the eighth consciousness is the overall fruit, it is the primary ruler of fruits, and other fruits are only then produced. Because the primary ruler leads and produces them, and because strong, superior karma leads the overall fruit, other particular, weaker karmas are only then able to produce fruits. In terms of its superior karma, it is termed "leading," because it leads other karmas to arise; the retribution is also termed "leading," because it leads other fruits. Karma is superior, so it is called "leading"; the fruit is uninterrupted, so it is said to "continue constantly." Because it continues constantly and is the leading fruit, it is given the name of "maturation fruit," and other dharmas are likewise.
