尼羯磨 3.120

3.120

爾時佛告諸比丘：「比丘至僧中先有五法：應以慈心；應自卑下如拭塵巾；應善知坐起，若見上坐不應安坐，若見下座不應起立；彼至僧中，不為雜說論世俗事，若自說法，若請人說法；若見僧中有不可事，心不安忍，應作默然，何以故？恐僧別異故。比丘應先有此五法，然後至僧中。」

At that time, the Buddha told the bhikṣus, "When a bhikṣu goes into the saṃgha, he should beforehand have five things: he should possess a mind of benevolence; he should humble himself like a dust-cloth; he should be well aware of sitting and standing, not remaining seated comfortably if he sees a senior, and not standing up if he sees a junior; when he arrives in the saṃgha, he should not engage in miscellaneous chatter discussing worldly affairs, but should either preach the Dharma himself or invite another to preach the Dharma; if he sees unacceptable things in the saṃgha and his mind cannot bear them with patience, he should remain silent. Why? Because he fears causing schism in the saṃgha. A bhikṣu should beforehand have these five things, and only then go into the saṃgha."
