大比丘三千威儀 1.61

1.61

復有五事：一者不得與女人連席坐；二者若賢明醫師不得從問諸藥諸事；三者不得與世人諍語；四者母人與比丘對坐，不得妄說不急事；五者設見因緣不可意，即當起去。

There are further five matters: first, one must not sit on the same mat connected with a woman; second, if one encounters a wise and skilful physician, one must not inquire of him about medicines and related matters; third, one must not quarrel and argue with worldly people; fourth, when a woman sits opposite a bhikṣu, he must not speak thoughtlessly of non-urgent matters; fifth, if one sees conditions that are unsuitable, one should immediately rise and depart.
