俱舍論疏 2.90

2.90

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."
