1.102

四十九恚忿心手搏　此亦六群既不得打。便舉指擬搏。令彼怖㖒。凡若手若脚若杖。舉以擬人悉犯墮。若舉餘身分犯突。為防毒狩惡人無犯。

Forty-nine: raising the hand to strike with an angry mind. Here too, when the ṣaḍvargika monks were no longer permitted to strike, they then raised their fingers to simulate striking, making the others terrified and weep. In general, whether with hand, foot, or staff, raising it to threaten a person is in every case an offense of pāyattika. If one raises another part of the body, it is a duṣkṛta. There is no offense if it is to guard against venomous beasts or evil persons.
