大比丘三千威儀 1.64

1.64

有七事不應往：一者不得妄往候事；二者不得事事往到；三者不得強往從請事；四者設往不得為說諸藥事；五者若呼比丘問世間事、若難異經；六者呼比丘教相星宿、視歲善惡；七者比國起兵，欲呼比丘宜軍事。如賢者不應往。

There are seven matters for which he should not go: first, one must not go thoughtlessly to inquire about secular affairs; second, one must not go there for every little thing; third, one must not push forward to go and make requests of them; fourth, if one goes, one must not speak to them about medicines; fifth, if they summon the bhikṣu to ask about worldly affairs, or to dispute unusual texts; sixth, if they summon the bhikṣu to teach astrology or observe the auspiciousness or inauspiciousness of the year; seventh, if neighbouring states take up arms and wish to summon the bhikṣu to consult on military affairs. In such cases, a virtuous person should not go.
