恐怖比丘戒第五十五　制意者。凡出家人宜須持護。不相惱觸。今以六塵等事遞相。恐怖令彼惶悸。廢修正業。事惱殊深。故須制斷　別緣有五。一大比丘。二作恐怖意。三以六塵等事。一一說示。四言辭了了。五前人見聞觸知便犯。已下正明戒本。此戒因那迦波羅反被拘執衣。欲怖佛令還入房。佛便呵責。制斯戒本。

Precept 55: On frightening a bhikṣu. The intention behind the enactment is: in general, those who have gone forth must support and protect one another, not troubling or disturbing each other. Now, mutually frightening one another by means of matters of the six sense objects causes the other person to be alarmed and terrified, neglecting the cultivation of their proper practice. The disturbance caused by this matter is exceedingly deep, so it had to be prohibited and ended. There are five specific conditions: 1. a great bhikṣu; 2. having the intention to frighten; 3. demonstrating each of the matters of the six sense objects one by one; 4. the words are distinct; 5. the previous person sees, hears, touches, or perceives it, whereupon the offense is committed. Below, the text of the precept is properly explained. This precept arose because Nāgapāla put on a skin cloak inside out, intending to frighten the Buddha into returning into his room. The Buddha then rebuked him and enacted this precept.
