大般涅槃經義記 3.159

3.159

上來對問正明人依，自下第二對昔會通。昔法今人，二言相異，故須會之，亦即明其行所依法。迦葉先問，問中先舉昔所說法非四種人，對人徵問。前中如說，「當依四法」總舉昔言，「何等」下別，「如是」下結。

Above, in response to the questions, it directly clarified the persons to rely upon; from here on is the second part: reconciling with the past teachings. Formerly it was dharmas and now it is persons; since the two statements differ, they must be reconciled, which also clarifies the dharmas upon which one's practice relies. Kāśyapa asks first; within his question he first raises the dharmas spoken in the past that are not the four kinds of persons, questioning in contrast to the persons. Within the former, as stated, "one should rely on four dharmas" broadly cites the past words; from "what are" onward distinguishes them; from "such" onward concludes.
