大般涅槃經義記 6.92

6.92

前中約對四人辯之：一明為化凡夫眾生而說是偈，彰彼凡夫有所得義。凡夫之人現有生死染污之法名為本有，現無出世涅槃淨法說為今無；現無出世涅槃淨法故名本無，現有生死染污之法說為今有。凡夫本有生死之法，三世常有無是處故，當必除捨；本無淨法，三世常無無是處故，當必得之，故非無得。

In the former part, it is explained in relation to four kinds of persons: First, it explains that he spoke this verse in order to transform ordinary beings, demonstrating the meaning of ordinary beings having attainment. For ordinary persons, currently having the defiled dharmas of birth-and-death is called "originally having"; currently lacking the pure dharmas of supramundane nirvāṇa is spoken of as "now lacking"; currently lacking the pure dharmas of supramundane nirvāṇa is called "originally lacking"; currently having the defiled dharmas of birth-and-death is spoken of as "now having". For ordinary beings, their originally having the dharmas of birth-and-death cannot possibly exist constantly throughout the three times, and so they will certainly eliminate and abandon them; their originally lacking pure dharmas cannot possibly be non-existent constantly throughout the three times, and so they will certainly attain them. Therefore, it is not non-attainment.
