大般涅槃經義記 9.249

9.249

自下第三就其一語明陰界入攝性周盡。先論一語，後約辨性。前中，「如來或為一法說無量法」總以標舉。為彰一法攝法周盡，說無量法同歸一法。「如經中」下，三番顯之。中約辨性，文顯可知。

From here below, third, with respect to the one speech, it clarifies that the aggregates, realms, and sense fields completely subsume the nature. It first discusses the one speech, and afterwards distinguishes the nature with reference to it. In the former, "the Tathāgata sometimes expounds immeasurable dharmas for the sake of one dharma" presents the general heading. To show that one dharma subsumes dharmas completely, immeasurable dharmas are taught as converging into one dharma. From "as in the sūtra" onwards, it is demonstrated in three turns. In the middle, the nature is distinguished with reference to it; the text is clear and can be understood.
