Revākhaṇḍa ascribed to the Vāyupurāṇa (RKV) 44.20

44.20

dattvā piṇḍodakaṃ tatra piṇḍāṇāṃ ca tathākṣayam /
yas tatra kurute śrāddhaṃ toyaṃ pibati nityaśaḥ /
mucyate sarvapāpaistu uragaḥ kañcukairiva /
anindyānpūjayed viprān dambhakrodhavivarjitān //

Offering rice-balls and water there yields inexhaustible [fruits] for the ancestors. / Whoever performs a śrāddha there and continually drinks its water / is freed from all sins, like a snake from its sloughs. / One should honor blameless brahmins who are free from deceit and anger.
