二、漉法者。《薩婆多》云：「欲作住處，先看水中有蟲否。有者，作餘井。猶有者，捨去。凡用水法應清淨者，如法漉置一器中，足一日用，令持戒審悉。漉竟，著淨器中，向日諦視看。故有者，如前說。」（即作餘井捨去。）然水陸空界，無非皆是有情依處。《律》中且據漉囊所得，肉眼所見，以《論》持犯耳。

Second, the method of straining. The Sarvāstivāda says: "When wishing to make a dwelling, first inspect whether there are living creatures in the water. If there are, dig another well. If there are still creatures, abandon it and leave. In all cases where the method of using water requires it to be pure, strain it according to the Dharma and place it in a vessel, sufficient for one day's use, having someone who maintains the precepts inspect it thoroughly. When straining is finished, place it in a clean vessel and gaze at it carefully toward the sun. If creatures still exist, proceed as said before." (That is, dig another well or abandon it and leave.) However, in the realms of water, land, and sky, there is nowhere that is not a dwelling place for sentient beings. In the Vinaya, one discusses holding and breaking [precepts] merely based on what is captured by the water strainer and seen with the fleshy eye.
