梵網經菩薩戒本疏 5.45

5.45

Seventh, permission and prohibition: By reasoning, keeping [them] to protect the Buddha-Dharma and to subdue sentient beings should incur no offense; also, if one begs and obtains them from evil people with the intention of destroying them, and has not yet destroyed them, there is no offense. Contrary to the above, in all cases keeping them incurs an offense. Therefore, when a bodhisattva sees others keeping them, they should exhort them to destroy them; if exhortation fails, one should beg for them or ransom them; if that still fails, one should use intimidation and the like (supervising and dispatching) and must make them stop.
