四分律刪補隨機羯磨 2.201

2.201

（《律》中：「若安居中，本二、大童女、婬女、伏藏，欲來誘調比丘；又有惡鬼、怨賊、毒蟲、惡獸，不得如意醫藥、使人。我若此住，必為我淨行及命作留難。佛言：『聽去。』」准《毘尼母論》云：「移夏不破安居。」諸部無文開。）

(In the Vinaya: "If during the retreat, one's former wife, a grown maiden, a courtesan, or hidden treasures come to seduce and harass a bhikṣu; or if there are evil spirits, hostile bandits, poisonous insects, or ferocious beasts, or if one cannot obtain suitable medicine or attendants, [and the bhikṣu thinks,] 'If I stay here, it will surely cause difficulties for my pure conduct and my life'—the Buddha said: 'I permit him to depart.'" In accordance with the Vinayamātṛkā: "Moving one's retreat does not break the retreat." Other traditions do not contain text granting this allowance.)
