大般涅槃經義記 7.187

7.187

如畏人下合上求度，文別有三：一合畏故「取草為筏」，先牒前喻，後合可知；二「依乘此」下超合向前推筏水中，身倚而去；三「修涅槃者作是思」下却合更思「我設住此，當為蛇等之所危害，寧沒水死，終不為彼蛇賊所害」，「以忍受故不生漏」者結明菩薩能斷念漏。「菩薩尚」下舉因況果，明佛無漏。

From "Like a fearful person..." downward applies to seeking to cross as mentioned above. The text distinctly has three parts: 1. it applies "taking grass to make a raft" out of fear; it first cites the previous parable, and the subsequent application can be understood; 2. from "relying on and riding this..." downward leaps forward to apply pushing the raft into the water, leaning upon it, and departing; 3. from "one who cultivates nirvāṇa reflects thus..." downward turns back to apply further reflecting, "If I stay here, I will be harmed by the snakes and so forth; better to drown in the water and die, never to be harmed by those snakes and thieves." "Because of enduring, not giving rise to outflows" concludes by explaining that the bodhisattva can sever the outflows of thoughts. From "If even a bodhisattva..." downward raises the cause to illustrate the result, explaining that the Buddha is free of outflows.
