8.32

又僧祇律云。一切道俗七眾等。並須漉水飲用。若漉得水已。使能見掌中細文者。審悉看之。看時如大象載竹車迴頃。知無應用。使可信者教漉。不可信者自漉。得蟲還送本取水來處安之。若來處遠近有池井。七日不消者。以蟲著中。若知水有蟲。不得持器繩借人。若池江水有蟲。不得唱云此水有蟲。若問者。答云。長者自看。若知友同師者。語言此中有蟲當漉水用。又十誦律。有二比丘。未曾見佛。從北遠道。共往舍衛奉見世尊。道中渴乏。值有蟲水。破戒者言。可共飲之。持戒者言。水中有蟲何可得飲。破戒者言。我若不飲。必當渴死不得見佛。便飲而去。持戒者慎護戒故不飲。遂渴乏死。即生三十三天。身得具足。先到佛所頭面禮足。佛為說法得法眼淨。受三歸畢還歸天上。時飲水者後到佛所。佛為四眾說法。即披衣示金色身。汝癡人欲看我肉身。何為不如持戒者。先見我法身智慧之身。佛言從今已去。比丘若行二十里外。無漉水囊犯罪。若自無同意伴有者聽去。

Furthermore, the Mahāsāṃghika-vinaya says: All the seven assemblies of both clergy and laity must filter water before drinking and using it. When the water has been filtered, have someone who can see the fine lines in the palm of their hand inspect it carefully. When inspecting, the time it takes is about as long as a large elephant turning a bamboo cart around; when it is known to be free [of organisms], it may be used. Have a trustworthy person be instructed to filter it; if someone is not trustworthy, filter it yourself. If insects or organisms are found, carry them back to the original place from which the water was taken and place them there. If the place of origin is distant, and there is a nearby pool or well where water does not dry up for seven days, place the insects inside. If you know that water contains insects, you must not lend the vessel and rope to others. If the water in a pool or river contains insects, you must not call out, "This water has insects!" If someone asks, answer, "Elder, look for yourself." If they are friends or fellow disciples of the same master, say to them, "There are insects here; you should filter the water before using it." Also, the Daśabhāṇavāra-vinaya states: There were two bhikṣus who had never seen the Buddha. Traveling from a distant land in the north, they went together to Śrāvastī to pay homage to the Bhagavat. On the road, they were parched with thirst and came upon water with insects. The one who broke the precepts said, "We can drink it together." The one who upheld the precepts said, "There are insects in the water; how can we drink it?" The one who broke the precepts said, "If I do not drink, I will surely die of thirst and never see the Buddha." He then drank and went on. The one who upheld the precepts, carefully guarding the precepts, did not drink and subsequently died of thirst. He was immediately born in the Heaven of the Thirty-Three, his body fully perfected. Arriving first before the Buddha, he bowed his head and touched the Buddha's feet. The Buddha preached the Dharma for him, and he attained the purity of the Dharma-eye. Having completed taking the Three Refuges, he returned to heaven. The one who had drank the water arrived before the Buddha later. The Buddha was preaching the Dharma for the fourfold assembly, and, opening his robes, revealed his golden body, [saying,] "You foolish man wished to see my physical body; why are you not like the one who upheld the precepts, who first saw my dharmakāya, the body of wisdom?" The Buddha said, "From this day forward, if a bhikṣu travels more than twenty li without a water-filtering bag, he commits an offense. If he does not have one himself, but a traveling companion of like mind has one, he is permitted to go."
