大般涅槃經義記 7.121

7.121

第二段中，「當知如來亦復不定」總以標舉，下別顯之。別中，初先開列章門，後廣辯釋。前開門中，若合地獄、畜生、餓鬼，有十九門，分之則有二十一門。就初門中，先明非天，次明非非。下雙結之，明非天中，「如來非天」總以標舉，「何以」下釋。上來數說佛天中天，今以何故言佛非天？下對釋之，先舉四天，次列四名。世間天者，《智度論》中名假合天，淨天、義天，《智度論》中通名淨天。次辯其相，下將如來對之顯非，「然眾生」下明非非天，「是故」下結。餘門可知。

In the second section, "You should know that the Tathāgata is also not fixed" raises [the topic] generally, and below it reveals it in detail. In the detailed part, it first opens and lists the thematic headings, and later extensively explains and clarifies them. In the previous opening of headings, if the hells, animals, and hungry ghosts are combined, there are nineteen headings; if divided, there are twenty-one headings. Within the first heading, it first clarifies that he is not a deva, and next clarifies that he is not a non-[deva]. Below, it concludes them both. In clarifying that he is not a deva, "The Tathāgata is not a deva" raises it generally, and from "Why?" downward explains it. Above, it repeatedly said that the Buddha is the deva among devas; now for what reason does it say that the Buddha is not a deva? Below, it explains in response: first it adduces the four kinds of devas, and next lists the four names. As for conventional devas, in the Zhidu lun (Mahāprajñāpāramitopadeśa) they are called "devas by nominal aggregation"; pure devas and devas of meaning are both collectively called "pure devas" in the Zhidu lun. Next it clarifies their characteristics, and below takes the Tathāgata to contrast with them to show that he is not [them]. From "Yet sentient beings" downward clarifies that he is not a non-deva, and from "Therefore" downward concludes. The remaining headings can be understood.
