梵網經菩薩戒本疏 5.155

5.155

Seventh, permissible and non-permissible cases: if one is ill oneself, or lacks capacity, or the other genuinely lacks virtue though appearing to have virtue, or if it is to tame the other, or to tame other sentient beings, or if the delusion of arrogance is fierce and violent while the power of counter-remedies is weak, there should also be no offense. If it is due to indolence, one commits a minor offense; the opposite of the above are all grave.
