大般涅槃經義記 8.124

8.124

自下第六如來答問，於中經文麁判有二：一略顯證義；二佛性者非內、非外，「然非失」下廣顯證義。細分有四：一對前八問略顯證法、二「若男女欲見如來應當修習十二部」下約對前法勸修趣入略明證行、三「性非內外然非失」下廣顯證法、四「師子言無相定者名涅槃」下約對前法勸修趣入廣明證行。

From here below is the sixth [part], the Tathāgata's answering of the questions, wherein the sūtra text, roughly divided, has two parts: first, briefly revealing the meaning of realization; second, from "The buddha-nature is neither internal nor external, yet it is not lost" onward, broadly revealing the meaning of realization. In a detailed division there are four: first, in response to the preceding eight questions, briefly revealing the dharma of realization; second, from "If a man or woman wishes to see the Tathāgata, they should cultivate the twelve divisions [of scriptures]" onward, with reference to the preceding dharma, exhorting cultivation to gain entry, briefly clarifying the practice of realization; third, from "The nature is neither internal nor external, yet it is not lost" onward, broadly revealing the dharma of realization; fourth, from "Siṃhanāda said: 'The concentration without marks is called nirvāṇa'" onward, with reference to the preceding dharma, exhorting cultivation to gain entry, broadly clarifying the practice of realization.
