As a disciple of the Buddha, I shall not kill, encourage others to kill, kill by expedient means, praise killing, rejoice at witnessing killing, or kill through incantation or deviant mantras. I must not create the causes, conditions, methods, or inclination of killing, and shall not intentionally kill any living creature.
As the Buddha’s disciple, I must nurture a mind of compassion and filial piety, always devising expedient means to rescue and protect all beings. If instead, I fail to restrain myself and kill sentient beings without mercy, I commit a major offense.
