大般涅槃經義記 7.31

7.31

「云何不生不生」問第二句，「是大涅槃無生相」者，涅槃體寂是一不生，而復不為生相所生是二不生。「是名」下結，是中不欲明涅槃法。約涅槃法明生死身不生不生，要得涅槃方乃得為不生不生，故就論之。

"What is meant by non-arising non-arising?" questions the second clause. "This Mahāparinirvāṇa has no characteristic of arising": the quiescent essence of nirvāṇa is one "non-arising"; and further, not being produced by the characteristic of arising is the second "non-arising." From "this is called" downward concludes. Herein, it does not intend to clarify the dharma of nirvāṇa [itself]; it clarifies the non-arising non-arising of the body of birth and death with reference to the dharma of nirvāṇa. One must attain nirvāṇa before one can attain non-arising non-arising; hence it discusses it in this manner.
