俱舍論疏 2.90

2.90

論「異熟因所生至故作是說」，釋異熟生。文中有四：此第一釋。「異熟因所生」者，因名異熟。果名異熟生者，屬主釋也。異熟因所生，故名異熟生，略去因所二字，名異熟生。喻意可解。此但釋果名異熟生所以，不說因名異熟因所以。

On the text of the treatise: "Born of a cause of maturation… therefore it is stated thus": This explains "born of maturation." In the text there are four: this is the first explanation. In "born of a cause of maturation," the cause is called maturation. That the fruit is called "born of maturation" is a genitive compound (tatpuruṣa). Born of a cause of maturation, it is therefore called "born of maturation"; abridging and omitting the two words "cause" and "of," it is called "born of maturation." The point of the analogy is intelligible. This merely explains the reason why the fruit is called "born of maturation"; it does not state the reason why the cause is called "cause of maturation."
