俱舍論頌疏論本 7.12

7.12

Explanation: The first two lines explain the causal condition, the third line explains the two conditions, and the fourth line concludes the activity, applying to all preceding three lines. 'Two causes [act] at the point of cessation' means that the two causes—associated and coexistent—exercise their activity at the point of cessation. 'At the point of cessation' refers to the present time; because this characteristic of cessation resides in the present, it is called the point of cessation. The word 'activity' here refers to the function of giving effect, because these two causes cause co-arising effects to have activity.
