成唯識論述記 2.712

2.712

述曰：前等流因是因緣種，其所生果即通八識種，此異熟因增上緣種，即是有分熏習種子，不以所生異熟之果顯其因性，但舉此因能變之因以彰自體。義顯所生除第七識，可通餘識及五蘊等無記之法，此體唯通善、惡二性，果唯無記。前因因果皆通三性，第七識唯無記，非異熟因，勢力羸劣不感果也，此非異熟，有覆性故。第八不能熏，此中皆不說。

The Commentary states: The previous cause of natural outflow is the seed of the cause-condition, and the fruits it produces extend to the seeds of all eight consciousnesses; this cause of maturation is the seed of the predominant condition, namely the seed perfumed by factors of existence. It does not reveal the causal nature by means of the maturation fruit produced, but only adduces this transforming cause of the cause to make manifest its own substance. It implicitly reveals that that which is produced, excluding the seventh consciousness, can extend to the remaining consciousnesses, the indeterminate phenomena of the five aggregates, and so forth. Its substance extends only to the two natures of wholesome and unwholesome, while its fruit is exclusively indeterminate. In the previous [natural outflow], both cause and fruit extend to the three natures; the seventh consciousness is exclusively indeterminate and is not a cause of maturation, as its potency is weak and does not induce karmic fruit; this is not maturation because it is of an obscured nature. The eighth cannot perfume; neither of these is discussed here.
