佛說目連問戒律中五百輕重事經 1.58

1.58

問：「結界為云何？」答：「結界法。若山澤無人處隨意遠近，若在城邑聚落不得遠結，亦不得夜結。結時要須比丘在四角頭立，不得使外人入，外人入則界不成。先結界場，僧家白衣奴子盡著界場上，然後視度四方。結界時除四處：一者聚落；二者聚落外俗人田地常作事處；三者若有阿練、若獨處山澤，恐說戒羯磨時有種種事難不得來，白眾求別結小界，眾若聽可，彼無五人眾，當遣僧與結別界，此謂阿練若坐處；四者受戒場，先結界文均除，結戒場，除是結界以是其事，或先結大界、後結戒場，於中受戒。如界公所云，恐無所獲。然云不知，同於取別顯通，此路可有僥倖。其人云，若有病比丘，不能得往僧中，求索別一屋中結界，僧亦應聽，先解大界，與結別界訖，然後結大界，一切比丘不持衣，夜中得入中。有一住處有界，一比丘亦可打揵槌廣說戒，先向四方僧懺悔，然後說，亦可三語。三語者，謂三說。」

Question: "How is the demarcation of a sīmā performed?" Answer: "The method of demarcating a sīmā: in uninhabited places such as mountains and marshes, it may be as far or near as one pleases. If in towns, cities, or villages, one must not demarcate it too far away, nor may one demarcate it at night. When demarcating it, bhikṣus must stand at the four corners, and outsiders must not be allowed to enter; if an outsider enters, the sīmā is not validly formed. First demarcate the sīmā grounds: gather all the laypeople, slaves, and servants of the saṃgha onto the sīmā grounds, and then survey the four directions. When demarcating the sīmā, exclude four places: first, villages; second, secular people's fields and places of regular work outside the village; third, if there is an araṇya [dweller] living alone in the mountains and marshes, who fears that at the time of reciting the precepts and performing karmans various obstacles and difficulties may prevent him from coming, he announces to the saṃgha and requests to establish a separate small sīmā; if the saṃgha consents, and there is no five-member saṃgha there, monks should be dispatched to establish a separate sīmā for him—this refers to the dwelling place of an araṇya dweller; fourth, the ordination platform: when demarcating the sīmā previously, this text excludes it equally—demarcating an ordination platform, except when demarcating the sīmā for this purpose; or one first establishes the great sīmā and later demarcates the ordination platform, receiving ordination within it. As the boundary official said, it is feared that nothing would be gained. Yet saying one does not know is the same as taking a separate view to show commonality; in this path there may be good fortune. That person said: if there is a sick bhikṣu who cannot go into the saṃgha, and he requests to establish a sīmā in a separate room, the saṃgha should also consent. First dissolve the great sīmā, establish the separate sīmā for him, and after that establish the great sīmā; all bhikṣus who do not take their robes may enter it at night. In a single dwelling place that has a sīmā, a single bhikṣu may also strike the ghaṇṭā and extensively recite the precepts; first repenting towards the saṃgha of the four quarters, and then reciting; or he may make three declarations. 'Three declarations' means reciting three times."
