俱舍論疏 2.92

2.92

論「彼所得果至故名異熟」，第三釋也。此即果是無記，因是善、惡。與因別類，名之為異。復是所熟，名為異熟。異熟即生，名異熟生，持業釋也。

On the text of the treatise: "The fruit obtained from it… is therefore called maturation": This is the third explanation. Here, the fruit is indeterminate, while the cause is wholesome or unwholesome. Differing in class from the cause, it is termed "different" (vi-). Furthermore, being that which is ripened, it is termed "maturation" (-pāka). Maturation is itself that which is born, termed "born of maturation," which is an appositional compound (karmadhāraya).
