1.273

問：「食巾或少多，將菜飯捉墮上，要須浣不？」答：「不污亦須曰浣。若有沙彌白衣，付之曰從受，不犯。若已付，著室中無苦。若不付又不浣，犯捨墮。」

Question: "If a dining napkin, whether small or large, has greens or rice dropped onto it, must it be washed?" Answer: "Even if not soiled, it must still be washed daily. If there is a novice or a layperson, one may entrust it to him and receive it from him daily, and there is no offence. If already entrusted, keeping it in the room causes no harm. If one neither entrusts it nor washes it, it is an offence of naiḥsargika-pātayantika."
