俱舍論記 6.219

6.219

「俱有相應至名士用果」者，釋第四句。此二因同得俱生勝士用果。雖復六因皆取士用，相應、俱有能取同時勝士用果，此中偏說。為遮勝論於法體外別有業用，故言非越士體有別士用。即此二因士用所得之果名士用果，從喻為名，如士夫用名為士用，士用之果名士用果。

Regarding "Simultaneous and associated [causes] ... are called the fruit of human effort": it explains the fourth line. These two causes together obtain the superior, simultaneously arising fruit of human effort. Although the six causes all take [the fruit of] human effort, associated and simultaneous causes are able to take the superior, simultaneous fruit of human effort, which is discussed exclusively here. In order to refute the Vaiśeṣika view that outside the substance of a dharma there is a separate activity, it therefore says "not exceeding the substance of the agent is there a separate human effort." The fruit obtained precisely by the effort of these two causes is named the fruit of human effort (puruṣakāra-phala), named from an analogy: just as a man's effort is called human effort, the fruit of human effort is named the fruit of human effort.
