大般涅槃經義記 2.143

2.143

上來第一明因得果，自下第二總以結嘆。「佛法不思」結嘆前因，「如來不思」結嘆上果。「迦葉白」下，大段第三領解奉行。初先領解。「如是如是，誠如聖教」，領前廣說佛法不思；「如來亦爾」領後結嘆；「故知」已下彰己奉行，先許自行，後為他說。自下第四如來述讚，先總嘆善，次勸正學，後明學益。

The above is the first part, clarifying the attainment of the fruit from the cause. From here on, the second generally concludes with praise: “The Buddha-Dharma is inconceivable” concludes with praise of the preceding cause; “the Tathāgata is inconceivable” concludes with praise of the aforementioned fruit. From “Kāśyapa addressed [the Buddha]” downward is the third major section, assimilating, understanding, and undertaking practice. First, he assimilates and understands: “Thus it is, thus it is, truly as the holy teaching says” assimilates the preceding extensive explanation that the Buddha-Dharma is inconceivable; “the Tathāgata is also like this” assimilates the subsequent concluding praise; from “therefore it is known” downward displays his own undertaking of practice, first pledging his own practice and later explaining it for others. From here on, the fourth is the Tathāgata's affirmation and praise: first generally praising it as good, next encouraging correct study, and finally clarifying the benefit of study.
