大般涅槃經義記 4.331

4.331

自下第五大眾請說，佛將為說口現無病。前中「爾時一切天」等標列請人，「悉共同」下見佛無病，讚喜共請，先讚、次喜。「說已踴躍」明其心喜，「或歌」口喜、「舞」等身喜。次供下請，先列請辭偈，後明其聲及遠近。

From here on, fifth, the great assembly supplicates for preaching, and the Buddha, about to preach for them, verbally manifests freedom from illness. In the former part: "At that time all the devas" and so forth marks and lists those who supplicate; from "All together with one voice" down, seeing the Buddha free from illness, they praise him, rejoice, and together make the supplication: first praising, next rejoicing. "Having spoken, they leaped with joy" explains their mental joy; "or singing" is vocal joy; "dancing" and so forth is physical joy. Next, making offerings and supplicating: first it lists the verses of supplication, and later explains their sounds and the distances [they reached].
