大般涅槃經疏 12.29

12.29

從「迦葉復白」下，是品中第九，答上云何諸菩薩而得不壞眾。迦葉更牒問為請，次佛答中還以護法為答。

From "Kāśyapa further addressed [the Buddha]" onwards is the ninth [section] within the chapter, answering the preceding [question], "How do the bodhisattvas obtain an unbreakable assembly?"
Kāśyapa again brings up the question to make a request, and next, in the Buddha's answer, he again answers by means of protecting the Dharma.
