金光明經文句記 3.59

3.59

二、「若作」下，約二緣釋。不殺有二：不殺是止善，放生是行善。不盜有二：不盜是止善，施食是行善。是故十善各有止行，悉名二緣。經於二善互舉止行，一一皆是長壽二緣，發菩提心方名為因。言法性者，無作四誓全法性起，是長壽因。種種二緣既能資助真正道心，乃會法報非常非無常，能起應化常與無常，三身一體斯為妙常。

Second, from 'If one takes' downward, explaining in terms of two conditions. Non-killing has two aspects: not killing is cessation-wholesomeness, and releasing living beings is action-wholesomeness. Non-stealing has two aspects: not stealing is cessation-wholesomeness, and giving food is action-wholesomeness. Therefore, the ten wholesome deeds each have cessation and action, all named two conditions. The sūtra alternately adduces cessation and action for the two wholesomenesses; each and every one is the two conditions for long lifespan. Generating the bodhicitta is alone named the cause. 'Dharma-nature' means that the uncreated four vows arise entirely from Dharma-nature and are the cause of long lifespan. Since the various two conditions can assist the genuine mind of the path, they unite Dharma and retribution as neither permanent nor impermanent, capable of generating response and transformation as permanent and impermanent; the three bodies being a single substance is this wondrous permanence.
