【鉢里薩羅伐拏】此云濾水羅。《會正記》云：「西方用上白㲲，東夏宜將密絹。若是生絹，小蟲直過，可取熟絹四尺，捉邊長挽，兩頭刺著，即是羅樣。兩角施帶，兩畔直怐（音冠，似鼎銨也），中安橫杖尺六，兩邊繫柱，下以盆承。傾水時，罐底須入羅內。如其不爾，蟲隨水落，墮地墮盆，還不免殺。」《僧祇》蟲細者三重漉。《毘尼母》應作二重漉水囊。若猶有，應作三重不得夾作。恐中間有蟲難出，當各作捲，逐重覆却，方護生也。《根本．百一羯磨》明五種水羅：一方羅，用絹三尺或二尺，隨時大小作；二法瓶，陰陽瓶也；三君遲，以絹繫口，以繩懸沈於水中，待滿引出；四酌水羅；五衣角羅，但取密絹，方一搭手，或繫瓶口，或安鉢中，濾水用也。

[Parisrāvaṇa] This is translated as "water-filtering strainer." The Huizheng ji states: "In the Western Regions, they use fine white cotton cloth; in China, one should take dense silk. If raw silk is used, small insects pass right through. One may take four feet of boiled silk, grasp the edges and pull them longwise, stitch the two ends together, and that is the pattern of the strainer. Attach straps at the two corners and straight loops at both sides (pronounced guan, resembling the handles of a caldron). Set a horizontal stick of one foot six inches in the middle, tie both sides to pillars, and place a basin beneath it. When pouring water, the bottom of the water jar must enter inside the strainer. If not done thus, insects will fall with the water, dropping to the ground or into the basin, and killing them is still not avoided." The Mahāsāṃghika Vinaya states that if the insects are minute, it should be filtered with three layers. The Vinayamātṛkā states: "One should make a water-filtering bag of two layers. If [insects] are still present, one should make three layers; they must not be sewn together as a double layer. Fearing that insects might be caught between them and difficult to release, one should make each layer separate, turning each layer over one by one; only then is life protected." The Mūlasarvāstivāda Ekottarakarma explains five kinds of water strainers: first, the square strainer, using three feet or two feet of silk, made large or small according to circumstance; second, the Dharma-vase, which is a yin-yang vase; third, the kuṇḍikā, with its mouth tied with silk, suspended with a rope and submerged in the water, and pulled out when full; fourth, the ladle strainer; fifth, the robe-corner strainer, where one simply takes dense silk one span square, and either ties it to the bottle's mouth or places it in the bowl, using it to filter water.
