17.53

第七明眾生皆愛身命與己無別。是故行者不應食肉。如彼經說。食肉能起色力貪味人多貪著。應當諦觀一切世間有身命者。各自寶重畏於死苦。護惜己身人畜無別。寧當樂存。疥野干身。不能捨命受諸天樂。何以故。畏死苦故。以是觀察死為大苦。是可畏法。自身畏死。云何當殺而食他肉。是故大慧。欲食肉者。先自念身。次觀眾生。不應食肉也。

Seventh, explaining that all sentient beings cherish their own lives no differently from oneself. Therefore, practitioners should not eat meat. As that sūtra says: 'Eating meat can give rise to physical strength and a craving for taste, which people mostly covet. One should attentively contemplate that all living beings in the world, each treasuring their own lives, fear the suffering of death; in guarding and cherishing their own bodies, humans and beasts are no different. They would rather cheerfully remain in the body of a mangy jackal than give up their lives to enjoy celestial pleasures. Why is this? Because they fear the suffering of death. Contemplating this, death is great suffering; it is a fearful thing. Since one's own body fears death, how could one kill and eat the flesh of another? Therefore, Mahāmati, one who wishes to eat meat should first reflect on their own body, then observe other sentient beings; they should not eat meat.'
