1.12

avigandhā rasopetā nirmalāḥ pṛthivīgatāḥ | akṣīṇāś caiva goḥ pānād āpaḥ śuddhatarāḥ smṛtāḥ || uddhṛtā vā praśasyante śuddhaiḥ pātrair yathāvidhi | ekarātroṣitās tās tu tyajed āpaḥ samuddhṛtāḥ

Having approached Devala, best of sages, / who was seated comfortably on the bank of the Indus, all the sages spoke these words:

Water on the ground that does not smell, has taste, is clear and is not exhausted by a cow's drinking is held the purest; or water drawn duly in pure vessels is praised; but water drawn and kept overnight one should throw away.
