金剛經纂要刊定記 3.26

3.26

佛苦下。通伏難。應先難云：「前引《纓絡女經》言不食，今經何以言食？」故此釋也。有說：「食欲至口，有威德天在側，隱形接至他方施作佛事，斯則示現而食，非真食也。」由是彼此皆不相違。

The passage beginning "The Buddha's bitter..." resolves a latent objection. One should first object: "The previously cited Yingluonü jing says he does not eat; why does the present sūtra say he ate?" Therefore, this explains it. Some say: "When the food was about to reach his mouth, there was a deva of majestic virtue at his side who invisibly took it and brought it to other directions to perform Buddha-work; this was a manifestation of eating, not true eating." Because of this, both do not contradict each other.
