大般涅槃經義記 10.137

10.137

自下第四明攝道法。根等九種是其道法，修起名攝。文中初先略以標舉，「若知根、因乃至畢竟名淨梵行」；「迦葉白」下問答廣論，先問、後答。答中先讚，後為辨釋。釋中，初先通解九法，根本因增；「云何異」下，別釋初三差別之相。

From here below, the fourth [section] clarifies subsuming the dharmas of the path. The nine kinds—root and so forth—are the dharmas of the path; practicing and raising them up is called 'subsuming.' In the text, he first briefly indicates and raises them: 'If one knows the root, the cause, up to the ultimate, it is called pure brahma-conduct.' From 'Kāśyapa addressed the Buddha' below, there is a question-and-answer broad discussion: first a question, then an answer. In the answer, he first praises and then discriminates and explains. In the explanation, he first generally explains the nine dharmas: root, base, cause, and increase; from 'How do they differ?' below, he distinctively explains the distinguishing characteristics of the first three.
