3.635

述曰：此即第七外人解質。未來因果，雖先有體，名因果時，要依作用，不依於體。未有作用名未來，正有作用名現在，作用已息名過去。現有因用，果用未生，因義既成，果義便立，故所詰難非預我宗。預者，關也。

The Commentary states: This is the seventh: the opponent explains the counter-question. Although future cause and effect previously have substance, when named 'cause' and 'effect,' they must rely on activity, not on substance. When activity has not yet occurred, it is called future; when actively functioning, it is called present; when activity has ceased, it is called past. In the present there is causal activity, while the fruit's activity has not yet arisen. Once the meaning of cause is established, the meaning of fruit is immediately set up; therefore, your cross-examination does not concern our school. "Concern" means relate to.
