菩薩戒本疏 1.36

1.36

The Buddha said: "Buddha-sons! Whether killing by oneself, having someone else kill, killing by expedient means, killing by praise, rejoicing upon seeing it done, or even killing by incantation; the causes of killing, the conditions of killing, the methods of killing, the karma of killing; down to anything that possesses life, one must not intentionally kill it. A bodhisattva should give rise to an abiding mind of loving-kindness and compassion, a mind of filial devotion, and by expedient means rescue and protect all sentient beings; if instead they indulge their own minds and kill living beings to their heart's content, this is a bodhisattva's pārājika offense."
