And, verily, the precepts, the sciences, the dialogue, the traditional myths and legends, and the Nârâsamsî Gâthâs are honey-offerings to the gods; and whosoever, knowing this, studies day by day the precepts, the sciences, the dialogue, the traditional myths and legends, and the Nârâsamsî Gâthâs, for his lesson, satisfies the gods with honey-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 Fathers, as their accustomed draughts.
