大般涅槃經義記 7.75

7.75

初中復三：一正就涅槃解不聞聞、二「德王白」下問答重論、三「德王白佛云何布施不得名為波羅蜜」下於前第二重顯義中有難解者問答重釋。初中先問，次對釋之。先解不聞名大涅槃出不聞體，「何故」已下釋不聞義，先徵、後解。「非有為」者不同生死，有為之法可以言論，故不可聞。「非音聲」者，不同能詮音聲性故，不可得聞。「不可說」者，不同名字可宣說故，不可得聞。下釋聞義，先徵後解，「以是」下結。

Within the first [part] there are again three: first, directly explaining "not hearing what is heard" in terms of nirvāṇa; second, from "King of Virtue said [to the Buddha]" downward, questioning and answering to discuss it again; third, from "King of Virtue said to the Buddha: Why does giving not obtain the name of pāramitā?" downward, questioning and answering to explain again points among the second reiteration of meaning that are difficult to understand. Within the first, he first asks, and next responds and explains it. He first explains that "not hearing" is called great nirvāṇa, showing the essence of "not hearing"; from "for what reason?" downward explains the meaning of "not hearing," first querying and then explaining. "Not conditioned" means that unlike saṃsāra, where conditioned dharmas can be discussed in speech, it therefore cannot be heard. "Not sound" means that because it is unlike the nature of expressive sounds, it cannot be heard. "Inexpressible" means that because it is unlike words and names that can be spoken, it cannot be heard. Below, he explains the meaning of "hearing," first querying and then explaining; from "for this [reason]" downward concludes it.
