俱舍論疏 7.62

7.62

論「已說因緣至方取境故」，此釋等無間緣及所緣緣作用時也。前二因於滅時，三因於生時，今等無間緣於生時，所緣緣於滅時，故言相違。生時滅時者，是果至生時、滅時也。言「作用」者，是與果也。

The treatise says: "Having explained the causal condition... only then apprehends the sensory object." This explains the times of activity for the immediate condition and the object condition. The previous two causes act at the time of cessation, and the three causes act at the time of arising; now, the immediate condition acts at the time of arising, and the object condition acts at the time of cessation. Therefore it is said that they are reciprocal. 'The time of arising and the time of cessation' refers to when the fruit reaches the time of arising and the time of cessation. 'Activity' refers to bestowing the fruit.
