大般涅槃經集解 26.5

26.5

案僧宗曰：此下舉八事，仰推如來不應有病也。智秀曰：此下有四翻，第一迦葉舉七復次事推佛無病、第二佛以神力現三種相、第三群生蒙益請佛說法、第四廣述無病以遣時情。

Sengzong notes: Below this, eight matters are raised to reverently infer that the Tathāgata ought not to have illness. Zhixiu says: Below this there are four rounds: first, Kāśyapa raises seven points to infer the Buddha is without illness; second, the Buddha uses supernormal power to manifest three kinds of marks; third, all beings receive benefit and request the Buddha to preach the Dharma; fourth, he extensively recounts freedom from illness to dispel the dispositions of the times.
