Sacred Books of the East, vol. 22: Gaina Sutras Part I, translated by Hermann Jacobi [1884], at sacred-texts.com
(Thus I say): He who acts rightly, who does pious work, who practises no deceit, is called houseless. (1) One should, conquering the world, persevere in that (vigour of) faith which one had on the entrance in the order; the heroes (of faith), humbly bent, (should retain their belief in) the illustrious road (to final liberation) and in the world (of water-bodies); having rightly comprehended them through the instruction (of Mahâvîra), (they should retain) that which causes no danger (i.e. self-control). Thus I say. (2) A man should not (himself) deny the world of (water-bodies), nor should he deny the self. He who denies the world (of water-bodies), denies the self; and he who denies the self, denies the world of (water-bodies). (3)
See! there are men who control themselves;
others pretend only to be houseless; for one destroys this (water-body) by bad, injurious doings, and many other beings, besides, which he hurts by means of water, through his doing acts relating to water. (4) About this the Revered One has taught the truth: for the sake of the splendour, honour, and glory of this life, for the sake of birth, death, and final liberation, for the removal of pain, man acts sinfully towards water, or causes others to act so, or allows others to act so. (5) This deprives him of happiness and perfect wisdom. About this he is informed when he has understood and heard from the Revered One, or from the monks, the faith to be coveted. There are some who, of a truth, know this (i.e. injuring) to be the bondage, the delusion, the death, the hell. For this a man is longing when he destroys this (water-body) by bad and injurious doings, and many other beings, besides, which he hurts by means of water, through his doing acts relating to water. Thus I say. (6)
There are beings living in water, many lives; of a truth, to the monks water has been declared to be living matter. See! considering the injuries (done to water-bodies), those acts (which are injuries, but must be done before the use of water, eg. straining) have been distinctly declared. Moreover he (who uses water which is not strained) takes away what has not been given (i.e. the bodies of water-lives). (A Bauddha will object): 'We have permission, we have permission to drink it, or (to take it) for toilet purposes.' Thus they destroy by various injuries (the water-bodies). But in this their doctrine is of no authority.
He who injures these (water-bodies) does not
comprehend and renounce the sinful acts; he who does not injure these, comprehends and renounces the sinful acts. (7) Knowing them, a wise man should not act sinfully towards water, nor cause others to act so, nor allow others to act so. He who knows these causes of sin relating to water, is called a reward-knowing sage. Thus I say. (8)
5:1 The water-lives which are treated of in this lesson are, as is the case with all elementary lives, divided into three classes: the sentient, the senseless, and the mixed. Only that water which is the abode of senseless water-lives may be used. Therefore water is to be strained before use, because the senseless lives only are believed to remain in water after that process.
