2.160

（佛言：「有三種安居：前安居、中安居、後安居。前安居者，住前三月。後安居者，往後三月。」《十誦律》，佛制五眾並令安居。《律》云：「尼不安居，波逸提。僧等四眾，突吉羅。」《明了論》云：「無五過處，得在中安居：一、大遠聚落，求須難得；二、太近城市，妨修出道；三、多蚊蟻，自他兩損；四、無可依人，可依人要具五德：一、求聞令聞；二、已聞令清淨；三、能決疑網；四、通達無滯；五、正見。五、無施主供給藥食。並不可安居。」《律本》云：「安居有四種：一、對首；二、心念；三、忘成；四、及界。」並有據緣，如下具列。）

(The Buddha said: 'There are three kinds of varṣā: the early varṣā, the middle varṣā, and the late varṣā. The early varṣā dwells for the earlier three months. The late varṣā goes for the later three months.' In the *Daśādhyāya-vinaya*, the Buddha enjoined all five assemblies to undertake varṣā. The *Vinaya* says: 'If a nun does not undertake varṣā, it is a pāyattika; for the four assemblies including monks, it is a duṣkṛta.' The *Arthaviniścaya* says: 'Where there are not the five faults, one may undertake varṣā in their midst: first, too far from a settlement, so that requisites are difficult to obtain; second, too close to a city, hindering cultivation of the path of departure; third, many mosquitoes and ants, causing harm both to oneself and to others; fourth, no person on whom one can rely—the person to rely upon must possess five virtues: 1. causing one who seeks hearing to hear; 2. causing what has been heard to be purified; 3. able to resolve the net of doubts; 4. having clear and unhindered comprehension; 5. right view. Fifth, no donors providing medicine and food. In all [such places], one must not undertake varṣā.' The root Vinaya says: 'There are four kinds of varṣā: 1. sammukhībhūta; 2. cetanā; 3. established through forgetting; 4. reaching the boundary.' All are based on conditions, as fully listed below.)
