菩薩戒本疏 2.71

2.71

佛言：佛子！不得以瞋報瞋、以打報打。若殺父母兄弟六親，不得加報；若國主為他人殺者，亦不得加報。殺生報生不順孝道，尚不畜奴婢打拍罵辱，日日起三業得罪無量，況故作七逆之罪？而出家菩薩無慈報讎，乃至六親中故報者，犯輕垢罪。

"The Buddha said: 'Disciples of the Buddha! You must not repay anger with anger, nor repay blows with blows. If parents, siblings, or the six kinds of kin are killed, you must not retaliate; if the ruler of the state is killed by others, you must likewise not retaliate. Killing living beings to repay [the debt of] life does not accord with filial piety. When even keeping male and female slaves and beating or reviling them, daily generating the three kinds of karmic actions, incurs limitless offenses, how much more so intentionally committing the offenses of the seven ānantarya sins? Yet if an ordained bodhisattva, lacking compassion, avenges an enemy, even intentionally retaliating among the six kinds of kin, they commit a duṣkṛta offense.'"
