梵網經菩薩戒本疏 6.27

6.27

七、通塞者，若重病不自由，若王力自在，若初發心未能賣身，理應不犯，反上皆犯。

Seventh, regarding permissible and non-permissible cases: if one is severely ill and lacks freedom, if constrained by the power of the king, or if being a beginner who is not yet able to sell one's body, in principle it should not constitute an offense; the reverse of the above are all offenses.
