律戒本疏 1.26

1.26

第五非親理尼浣染打故衣　迦留陀夷與掘多尼欲心相視漏失污衣。尼為浣之取計自灌。遂以有身惡名流布。因制。非親以妨惡緣。乃至一枕頭名為故打。一下名為打打浣染。於是三事中越一便犯。何況二三也。語莫打染。打染等犯者由先作方便欲令打故。若先實無心者不犯。云新衣未著故衣浣淨得倩摓也。浣時色脫。如本染竟更受。若猶有色雖染不須受也。青黃白紫等衣受。當三衣不戒受也。不淨色故也。

Fifth: An unrelated nun washing, dyeing, or beating an old robe. Kālodayin and the nun Guptā looked at each other with lustful minds, and an emission soiled his robe. The nun washed it for him and took the liquid to irrigate herself, whereupon she became pregnant, and a bad reputation was spread abroad. On this account [the precept] was instituted. [Requiring that she be] unrelated prevents evil conditions. Even [beating] a single pillow is called beating old [material]. A single blow is called beating. Washing and dyeing: in these three matters, transgressing a single one constitutes an offense, how much more so two or three! If one told her not to beat or dye it, but she beat or dyed it, and an offense is committed, it is because [the monk] previously employed an expedient wishing for her to beat it. If originally there was truly no such intention, there is no offense. It is said that for a new robe not yet worn, or an old robe that has been washed clean, one is permitted to ask [her] to sew it. If when washed the colour fades, once dyed as originally, it should be received again. If it still has colour, although dyed, it does not need to be received. If robes of blue, yellow, white, purple, etc., are received, when serving as the three robes, they are not received as precepts [matter], because their colour is impure.
