法華玄論 2.58

2.58

Answer: It has already been explained in the text. However, some claim that this refers to the text of the one vehicle and is not about nirvāṇa. We now clarify that this is not so: the sūtra text directly contrasts the lesser nirvāṇa to illuminate the great nirvāṇa; the lesser nirvāṇa is provisional and the great nirvāṇa is real. Therefore, the preceding verse explains it is not real extinction, and the subsequent verse explains true extinction.
