3.1086

第七，四獨戒。（佛在舍衛，有凡褰衣渡水，為賊觸嬈，人譏故制；尺有尼多諸弟子，捨眾，獨行入村；又於村中獨宿，人皆譏云：欲得男子。又六群尼，與眾尼於拘薩羅曠野中行，而常在後，人問，答云：欲得男子，訶已因制；四戒合制，隨一成犯。）若比丘尼，獨渡水，獨入村，獨宿（隨脇著地），獨後行（離伴見聞），犯初法應捨僧伽婆尸沙。

7. The precept on the four solitary acts. (The Buddha was in Śrāvastī. An ordinary nun hitched up her robes and crossed a river, where she was molested by thieves, and people censured her, hence the institution. Another nun had many disciples, abandoned the assembly, and went into a village alone; furthermore, she slept alone in the village, and everyone censured her, saying, 'She desires a man.' Furthermore, the bhikṣuṇīs of the group of six traveled with the assembly of bhikṣuṇīs in the wilderness of Kosala, but constantly lagged behind; when people asked them, they answered, 'We desire men.' Having rebuked them, the Buddha instituted the rule on this account. The four precepts were combined into one prohibition; any single one constitutes an offense.) If a bhikṣuṇī crosses water alone, enters a village alone, sleeps alone (whenever her flank touches the ground), or walks behind alone (separated from her companion's sight and hearing), she commits an offense requiring formal suspension upon the initial act.
