菩薩戒本疏 2.65

2.65

若佛子！以慈心故，行放生業，應作是念：一切男子是我父，一切女人是我母，我生生無不從之受生故。六道眾生皆是我父母，而殺而食者，即殺我父母，亦殺我故身。一切地水是我先身，一切火風是我本體，故常行放生，生生受生常住之法，教人放生。若見世人殺畜生時，應方便救護，解其苦難，常教化講說菩薩戒，救度眾生。若父母、兄弟死亡之日，應請法師講菩薩戒經，福資亡者，得見諸佛，生人天上。若不爾者，犯輕垢罪。

"Disciples of the Buddha! When, with a mind of compassion, one practices the deed of releasing living beings, one should think thus: 'All men have been my fathers, and all women have been my mothers; in life after life, there is none through whom I have not taken birth. Sentient beings of the six destinies are all my parents; therefore, to kill and eat them is to kill my parents and to kill my former body. All earth and water has been my past body; all fire and wind has been my original substance.' Therefore, one should constantly practice releasing living beings, for taking birth life after life is an eternally abiding principle, and teach others to release living beings. If one sees worldly people killing animals, one should skillfully rescue and protect them, liberating them from their suffering and difficulties, and constantly instruct and expound the bodhisattva precepts, rescuing and crossing over sentient beings. On the day a parent or brother dies, one should invite a Dharma master to lecture on the bodhisattva precept scripture, dedicating merit to aid the deceased so that they may see the Buddhas and be born in the human and heavenly realms. If one does not do so, they commit a duṣkṛta offense."
