瑜伽師地論略纂 11.24

11.24

論云「食所食時，有粒皆碎，無口不殫」，言佛食時，飯粒皆碎，無口不盡。殫，由盡也。又《攝論》說：佛食時，諸天得請餘處利益眾生。今此中言碎者，據有得碎義，其實化身示身，以佛事為正。

The treatise says, 'When eating what is eaten, all grains are crushed, and nothing in the mouth is left unexhausted.' It means that when the Buddha eats, all grains of rice are crushed, and in his mouth nothing is not finished. 'Dan' (殫) means 'exhausted'. Moreover, the Mahāyānasaṃgraha says: when the Buddha eats, devas are able to request [his presence] elsewhere to benefit sentient beings. Now, here, saying 'crushed' is based on the sense that there is crushing, but in reality, as a manifestation of the transformation body, its primary purpose is the Buddha's work.
