Verily, the Rik-texts are milk-offerings to the gods; and whosoever, knowing this, studies day by day the Rik-texts for his lesson, thereby satisfies the gods with milk-offerings; and, being satisfied, they satisfy him by (granting him) security of possession, by life-breath, by seed, by his whole self, and by all auspicious blessings; and rivers of ghee and rivers of honey flow for his (departed) Fathers, as their accustomed draughts.
