大般涅槃經義記 7.63

7.63

上來第五問答辯法，自下第六瑠璃領解。先踊在空七多羅樹，下正領解。「我蒙教誨，因大涅槃解聞、不聞」自身領解。領佛向前教己聽儀名蒙如來慇懃教誨，領佛向前解聞、不聞名因涅槃解聞、不聞。「亦令八萬四千菩薩解生、不生」，代眾領解。准此定知聞與不聞，為己故問；生與不生，為他故問。此二是前知密藏中兩種義也。

The above was the fifth [section], question and answer discerning the dharma. From here on is the sixth, Vaiḍūrya's expression of understanding. First, he leaps into the air to the height of seven tāla trees; below, he directly expresses his understanding. "Having received your instruction, based on the Great Nirvāṇa I understand hearing and non-hearing" is his personal expression of understanding. Acknowledging the Buddha's prior instruction to him regarding the etiquette of listening is called "having received the Tathāgata's earnest instruction"; acknowledging the Buddha's prior explanation of hearing and non-hearing is called "based on nirvāṇa understanding hearing and non-hearing." "And causing eighty-four thousand bodhisattvas to understand arising and non-arising" expresses understanding on behalf of the assembly. Based on this, one definitely knows that hearing and non-hearing were asked for his own sake, while arising and non-arising were asked for the sake of others. These two are the two kinds of meanings within the previously understood secret treasury.
