俱舍論疏 7.11

7.11

論「尊者世友至等無間緣」，敘異說也。由一身中先有一長養色相續不斷，後有第二長養色生，不相違害故，不立等無間緣。此師釋意闕開避義及雜亂不等故，不立等無間緣。

On the Śāstra's statement: "Venerable Vasumitra … equal-and-immediate condition": this recounts a divergent explanation. Because within a single body, there is first an unbroken continuity of a single nourished matter (aupacayika-rūpa), and subsequently a second nourished matter arises without obstructing or harming [the first], it is not established as an equal-and-immediate condition. The intention of this master's explanation is that because it lacks the sense of clearing the way and is confused and unequal, it is not established as an equal-and-immediate condition.
