成唯識論述記 8.263

8.263

The Commentary states: When the verse says "together", it means that the former karmas and the latter seeds of the two graspers are together; that is, they simultaneously bring about and generate the fruit, unlike the Hīnayāna where the ripening cause and fruit must belong to different time periods. Although the time of action and the time of receiving belong to different time periods, when the seed is directly receiving its fruit, it must belong to the same period as the fruit, because past and future periods lack real entity. Question: In the state of generating the fruit, what is direct is the causal condition, and if one considers the capability to bring about the fruit, what is superior is solely the karmic seed; or since both kinds [of seeds] are together, why does the verse state the karmic seed first and the causal condition afterwards?
