四分律刪繁補闕行事鈔 2.196

2.196

用蟲水戒十九。四緣：一是蟲水，二知有蟲，三不作漉法，四隨所用犯。律云：若以草土擲蟲水中。若蟲酪漿、清酪漿、若漬麥漿、若醋，有蟲，以澆泥草，若以草土擲中，一切皆墮；教人亦同。《五分》：隨用蟲，一一墮。律中若以草土擲水中，隨河池中魚蟲，一一提。《大集》云：畜生身細猶如微塵十分之一，乃至大者百千萬由延。《僧祇》：蟲細者，三重漉，猶有者，捨去。若用水者，日日諦視，無蟲便用；以蟲生無定，或先無今有故。《五分》：蟲水者，漉囊所得，肉眼所見；若用水，蟲蟲墮。無漉囊不得半由旬行，若無者用衣角漉之。律不犯中：不知有蟲，作無蟲想；若蟲大，以手動水令蟲去；若漉水洒地，若教人漉者，一切不犯。

Precept nineteen: using water with insects. There are four conditions: first, it is water containing insects; second, knowing that there are insects; third, not performing the filtration procedure; fourth, transgressing according to whatever use is made. The Vinaya states: 'If one throws grass or earth into water containing insects.' If there are insects in curds, whey, fermented barley water, or vinegar, and one uses it to pour over mud or grass, or if one throws grass or earth into it, all are pāyattikas; instructing another is also the same. The Pañcavargika-vinaya states: 'According to each insect used, each is a pāyattika.' In the Vinaya, if one throws grass or earth into the water, according to the fish and insects in the river or pool, each is a pāyattika. The Mahāsaṃnipāta states: 'The bodies of animals are as minute as a tenth of a fine speck of dust, up to large ones of hundreds, thousands, or tens of thousands of yojanas.' The Mahāsāṃghika-vinaya states: 'If the insects are minute, filter it three times; if there are still some, discard it. If one uses water, one should inspect it closely every day; if there are no insects, one may then use it, because the generation of insects is not fixed: either they were previously absent and are now present.' The Pañcavargika-vinaya states: 'As for water with insects, it refers to what is retained by a water-filter and can be seen by the fleshy eye; if one uses the water, for each insect it is a pāyattika. Without a water-filter, one may not travel half a yojana; if one lacks one, one should filter it using the corner of one's robe.' In the Vinaya's non-offenses: not knowing there are insects and conceiving the thought that there are no insects; if the insects are large, stirring the water by hand to cause the insects to leave; or if one sprinkles the ground with filtered water, or instructs another to filter it—in all such cases, there is no transgression.
