大般涅槃經義記 8.124

8.124

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.
