四分律刪繁補闕行事鈔 3.450

3.450

獨在後行。或根本獨去，或中間作意，離伴見聞處行；又伴無諸難緣，故犯。《四分》云：見聞俱離，殘；見聞互離，蘭。不犯中，開度水者，若共伴漸度，不失威儀；乘船、橋上、躡梁、躡石；伴尼死、休道、遠行、及諸雜難不得作伴，並開。《五分》：水淺，無畏男子處，不犯。開入村緣，如前具緣中。開獨宿者，律云：共二尼宿，舒手相及處；若一尼出大小便，或出受經誦經，若樂靜獨處誦經，或為病尼煮羹粥作飯，乃至餘難緣，並開。《僧祇》：若病，賊亂圍城，獨宿不犯。開獨行中，應在不離見聞處；若一尼大小便、諸難，皆開。《僧祇》：不得出聚落界，除道行便利，邂逅失伴，未及中間，不犯；病亦如是。《五分》：若恐怖走時，老病不及伴者，不犯。

Walking alone behind. Either fundamentally going alone, or midway forming the intention, walking apart from the companion's sight and hearing; furthermore, the companion has no grounds of distress; hence an offense is committed. The Dharmaguptaka Vinaya says: Separated from both sight and hearing, it is a saṃghāvaśeṣa; separated from either sight or hearing, it is a thullaccaya. Among non-offenses, allowances for crossing water: if crossing gradually with a companion, not losing proper deportment; riding a boat, on a bridge, stepping on beams, stepping on stones; if the companion nun dies, disrobes, travels far, and various mixed dangers prevent companionship, all are allowed. The Pañcavargika-vinaya states: Where the water is shallow and there are no men to be feared, there is no offense. Allowances for entering a village are as in the aforementioned complete conditions. Regarding allowances for staying overnight alone, the Vinaya says: Staying overnight with two nuns within reach of an outstretched hand; if one nun goes out to defecate or urinate, or goes out to receive or recite sutras, or delights in quietude to recite sutras in a solitary place, or cooks broth, gruel, or meals for a sick nun, up to other conditions of distress, all are allowed. The Mahāsāṃghika-vinaya states: If ill, or in times of bandit chaos or a besieged city, staying overnight alone is not an offense. Among allowances for walking alone, it should be where one is not separated from sight and hearing; if one nun defecates, urinates, or has various troubles, all are allowed. The Mahāsāṃghika-vinaya states: She must not leave the boundary of a settlement, except when relieving herself while traveling on the road; if she accidentally loses her companion and has not yet caught up, there is no offense; the same applies to illness. The Pañcavargika-vinaya states: If running in terror, or being elderly and sick and unable to catch up with the companion, there is no offense.
