俱舍論疏 30.207

30.207

論「如是雖言至差別生」，釋業生其果時，非無間生、非離業生，從彼業相續轉變差別生。

On the Śāstra's statement, "Thus, although it is said... arises from transformation and distinctiveness": this explains that when karma produces its fruit, it does not arise immediately, nor does it arise apart from karma; it arises from the continuum, transformation, and distinctiveness of that karma.
