大般涅槃經義記 6.227

6.227

上來偏就迦葉如來明《涅槃經》常有不滅，自下汎就餘佛如來明《涅槃經》常存不滅。於中有二：一明眾生異見生時諸佛乃說是《涅槃經》、二「寧說蚊嘴盡大海」下就不說時明實不滅。有六復次，皆先舉其假設之言，後顯不滅。

The preceding specifically clarified that the Mahāparinirvāṇa Sūtra constantly exists and is not extinguished with reference to Kāśyapa Tathāgata. From here below, it generally clarifies that the Mahāparinirvāṇa Sūtra constantly abides and is not extinguished with reference to other buddha-tathāgatas. Within this, there are two parts: first, clarifying that when divergent views arise among sentient beings, the buddhas then preach this Mahāparinirvāṇa Sūtra; second, from "Rather say that a mosquito's beak exhausts the great ocean" below, clarifying that it is truly not extinguished during the time when it is not preached. There are six instances, each first raising a hypothetical statement, and afterward demonstrating non-extinction.
