大般涅槃經義記 1.133

1.133

二「爾時大眾聞佛世尊普為」已下，因純陀請住，明佛應滅，實即不遷，無為故常。前中初因純陀啟請，略開常法；二純陀白佛，二施無差；「不然」已下因純陀設難，廣解常義。就初段中，先請、後答。請中，初先標列請人。「爾時會中」，彰其所在。「有優婆塞」，標別其人。此實大聖示居，始學導引不及。「是拘尸城」，出其住處。「工巧之子」，彰其種姓。「名曰純陀」，辯其名諱，「與其同類十五人俱」，兼列其眾。

Second, from "At that time the great assembly heard the Buddha, the World-Honoured One, universally for the sake of..." onward, relying on Cunda requesting [the Buddha] to remain, it clarifies that the Buddha responsively becomes extinct, but in reality does not transmigrate, and being unconditioned is therefore eternal. In the former part, initially relying on Cunda's request, the eternal Dharma is briefly opened; second, Cunda addresses the Buddha that the two givings are without distinction; from "Not so" onward, relying on Cunda posing a difficulty, the eternal meaning is extensively explained. In the first section, there is first the request, and afterward the answer. In the request, it first identifies and lists the person making the request. "At that time in the assembly" shows his location. "There was an upāsaka" identifies and distinguishes the person. This is actually a great sage manifesting his residence, whose guidance cannot be equaled by beginners. "Of this city of Kuśīnagara" indicates his dwelling place. "A son of an artisan" reveals his caste. "Named Cunda" discerns his name. "Together with fifteen companions of his kind" also lists his assembly.
