成唯識論述記 8.149

8.149

述曰：第二師說：五果體性寬、狹如前，但釋論文有盡理、不盡為異於前。此「習氣」言，唯屬十五依處中第三依處，雖此報因餘四處亦有，習氣中亦有非報因者，識等五種生現行是，以異熟因熟時去果相遠，習氣依處望果亦遠故，偏說習氣得異熟果，不言習氣並是報因，餘依處中無此因也。

The Commentary states: The second master says: The scope of the essential natures of the five fruits, in terms of breadth and narrowness, is as stated above; the only difference is that their explanation of the treatise text either exhausts the principle or does not exhaust it. Here, the word 'vāsanā' refers exclusively to the third basis among the fifteen bases. Although this cause of vipāka also exists in the other four bases, and there are also [seeds] within vāsanā that are not causes of vipāka—namely, the five kinds of seeds of consciousness and so forth when generating actual states—because the vipāka-cause is far removed in characteristic from the fruit when maturing, and the basis of vāsanā is likewise far removed with respect to the fruit, it is said specifically that vāsanā obtains the vipāka fruit. It is not meant that vāsanā is entirely the cause of vipāka, nor that this cause is absent in the other bases.
