俱舍論記 30.152

30.152

「由種展轉至轉變差別生」者，論主答。由初種子所有功能展轉付囑，引起華中生果功能。從初為名，故作是說種能生果。若此華內生果功能非種為先所引起者，所生果相應與種別，不應遠麥等似前麥因等。舉法同喻云：如是雖言從業生果，而非從彼已壞業生，亦非從業無間生。果但從前業相續、轉變、差別種生。

Regarding "Due to the seed successively … arises through transformation and culmination": the author of the treatise answers. Because the capacity possessed by the initial seed is successively transmitted, it brings about the capacity to produce the fruit within the flower. Naming it from the beginning, it is therefore said that the seed can produce the fruit. If this capacity to produce the fruit within the flower were not brought about preceded by the seed, the characteristic of the fruit produced should be different from the seed, and it would not remotely resemble the preceding barley cause, etc. Presenting the doctrine to match the analogy, it says: likewise, although it is said that fruit arises from karma, it does not arise from that already destroyed karma, nor does it arise from karma immediately. The fruit arises merely from the specific seeds of the continuum, transformation, and culmination of the previous karma.
