大般涅槃經義記 2.185

2.185

上來明其能開之德，自下第二明所開法。於中有三：一就涅槃微妙義中開出般若；二「若男子女人作如是言如來無常」下，就涅槃中開出法身；三「迦葉白佛如佛昔說無所積聚」下，就涅槃中開出解脫。前中初明波若四相，「假使有人作是言」下結彼四相即大涅槃。上來所辯是能開德，是故結之以屬菩薩；自下四相是所開法，是故結之以屬涅槃。

The above clarified the virtues of that which is able to reveal; the second [part] below clarifies the teachings that are revealed. Therein are three: first, revealing prajñā from within the subtle meaning of nirvāṇa; second, from "if a man or woman makes such a statement: 'the Tathāgata is impermanent'" downward, revealing the dharmakāya from within nirvāṇa; third, from "Kāśyapa addressed the Buddha: 'Just as the Buddha formerly said that there is nothing accumulated'" downward, revealing liberation from within nirvāṇa. In the former, it first clarifies the four marks of prajñā; from "suppose a person makes this statement" downward, it concludes that those four marks are precisely the great nirvāṇa. What was explained above was the virtue of that which is able to reveal, and therefore it was concluded as belonging to the bodhisattva; the four marks below are the teachings that are revealed, and therefore they are concluded as belonging to nirvāṇa.
