大般涅槃經義記 7.337

7.337

釋中有二：一通就諸法以彰七別；二「諸佛如來煩惱不起名涅槃」下就佛論七，明七無別。

Within the explanation there are two parts: first, it broadly addresses all dharmas to reveal the seven distinctions; second, from "The afflictions of all buddhas and Tathāgatas do not arise, which is called nirvāṇa" onward, it discusses the seven with respect to the Buddha, clarifying that the seven have no distinction.
