大般涅槃經義記 7.220

7.220

「世間名」下釋難顯常，成涅槃大。釋何等難？德王上言涅槃有名即是無常；佛今釋之，涅槃之名無而強立，故得為常，常故名大。經文之中雖不言常，其義正當。文中有二：一明涅槃無名強立、二「譬如有法不可稱」下約前所顯彰涅槃大。前中初先汎明一切世俗名字置立不同，先舉二門，後辯可知。下約顯法，「涅槃如是無因強立」，同向後門。於中初法，次喻，後合。

From "worldly designations" downward resolves a difficulty and reveals permanence, establishing the greatness of nirvāṇa. What difficulty does it resolve? The King of Virtuous Marks previously said that if nirvāṇa has a name, it is impermanent; the Buddha now resolves it: the name of nirvāṇa is non-existent yet forcibly posited, so it can be permanent, and because it is permanent it is called great. Although the sūtra text does not explicitly say permanence, its meaning properly corresponds to it. In the text there are two [points]: first, clarifying that nirvāṇa is nameless and forcibly posited; second, from "for instance, there is a dharma that cannot be weighed" downward, in terms of what was revealed before, highlights the greatness of nirvāṇa. In the first: it first broadly clarifies that the establishment of all conventional worldly names differs; it first raises two gates, and afterward analyzes them, as can be known. Below, it correlates them to reveal the dharma: "Nirvāṇa is thus without cause and forcibly posited," which corresponds to the latter gate. Within this, first is the dharma, next the metaphor, and finally the application.
