83.31

疏「皆言示者，久已降故」者，即《涅槃》第二「佛許受純陀之供，云：『純陀！施食有二，果報無差。何等為二？一者受已得阿耨多羅三藐三菩提、二者受已入於涅槃。』純陀不受此言，廣難如來，謂二女先施，是雜食身，非金剛身、常身、法身等，豈得言同？佛答云：『爾時破壞四魔，今入涅槃亦破四魔，是故我言亦施果報等無差別。』末後云：『如來之身已於無量阿僧祇劫不受飲食。』」釋曰：此身不受飲食，則顯此身久已降魔。

The commentary's 'All say "manifesting", because they were conquered long ago': That is, in the second fascicle of the Mahāparinirvāṇa-sūtra, 'The Buddha consented to accept Cunda's offering, saying: "Cunda, there are two kinds of offerings of food whose karmic retributions are without difference. What are the two? First, having received it, one attains anuttarasamyaksaṃbodhi; second, having received it, one enters nirvāṇa." Cunda did not accept these words and raised extensive objections to the Tathāgata, maintaining that the earlier offering by the two women was for a body sustained by coarse food, not an adamantine body, eternal body, dharmakāya, etc.—how could they be called identical? The Buddha replied, saying: "At that time I crushed the four māras, and now entering nirvāṇa I also crush the four māras; therefore I say the karmic retribution of the offerings is equal and without difference." At the very end it says: "The body of the Tathāgata has not received food or drink for immeasurable asaṃkhyeya kalpas."' Explanation: If this body does not receive food and drink, this reveals that this body conquered the māras long ago.
