第六非親理居士居士婦得衣　跋難陀多知辨說。強乞取衣。居士悔惜。瞋恚大喚賊向佛。佛即結戒。非親理勿乞。縷緣突。乞衣捨墮。若王若賊怨家所奪。若火曰所燒。若自失。若風水所標。以是因緣失衣聽求所。則父母親中俱取。七世上取。二祖及父下取。兒及二孫中取。自身為七世也。姨姑兄弟姉妹伯叔伯祖等。七世以內是親故也。小母伯叔母嫂等非親親也。赤麻胡麻衣也。翅姨羅者渚沙。染衣也。芻麻即縛麻衣也。無埿洹僧竭支得乞。

Sixth: Obtaining robes from an unrelated male or female householder. Upananda had much learning and eloquence. He forcibly begged and took robes, and the householder regretted and grudged it, shouting angrily in a loud voice, "Thief!" to the Buddha. The Buddha forthwith formulated the precept: "Do not beg from the unrelated." [Begging] thread or hems is a duṣkṛta; begging robes is a niḥsargika-pāyattika. If [robes] are seized by kings, thieves, or enemies; if burned by fire or sun; if lost by oneself; or if carried away by wind or water—if through such causes and conditions one has lost robes, one is permitted to seek them. One may take from among relatives on both parents' sides: looking up to seven generations, one takes from the two grandfathers and the father; looking down, one takes from sons and two generations of grandsons; in the middle, taking oneself, these make the seven generations. Maternal aunts, paternal aunts, brothers, sisters, paternal uncles, grand-uncles, and so forth within seven generations are relatives. Stepmothers, paternal uncles' wives, sisters-in-law, and so forth are not [consanguineous] relatives. Red hemp [robes] are sesame [hemp] robes. Kṣauma [robes] are dyed with river-shoal sand. Kṣauma is woven hemp robes. If one lacks an antarvāsa or saṃkakṣikā, one is permitted to beg for them.
