大般涅槃經義記 9.23

9.23

From "neither internal nor external" up to this point is the third major section, broadly revealing the realized Dharma. Below, the fourth section encourages cultivation to progress toward entry, broadly revealing realized practice. How does this differ from the realized practice in the preceding second section, such that it needs to be discussed again? In the former second section, it taught seeing the Tathāgata in order to progress toward true realization; now, in this text, it teaches seeing nirvāṇa: this is the first difference. Furthermore, the former text directly explained upholding the precepts and seeing the nature as the practice for progressing toward realization, without differentiating among persons; here it displays the gradations of practice according to persons: this is the second difference.
