大般涅槃經義記 10.134

10.134

自下第二辨出道體。於中初說《大般涅槃經》以為道法，後說三十七菩提分以為道行。法中，迦葉初先總問，「云何梵行」。如來總答，「一切法是」。迦葉重問，「一切不定，何等一切」。下佛先嘆；後為辨之，《涅槃經》是，於中初以四十二句別歎經勝、後總結嘆。

From here below is the second part, explaining the essence of the path. Herein, first it speaks of the *Mahāparinirvāṇa Sūtra* as the dharma of the path, and afterward speaks of the thirty-seven factors of awakening as the practice of the path. Within the dharma, Kāśyapa first asks generally: "What is the pure conduct (brahmacarya)?" The Tathāgata answers generally: "All dharmas are." Kāśyapa asks again: "'All' is indeterminate; what constitutes all?" Below, the Buddha first praises it; afterward, he explains it for him: the *Nirvāṇa Sūtra* is it, within which he first specifically praises the superiority of the sūtra with forty-two phrases, and afterward summarizes his praise.
