O Maker of the material world, thou Holy One! Is it true that thou, Ahura Mazda, seizest the waters from the sea Vouru-kasha with the wind and the clouds? That thou, Ahura Mazda, takest them down to the corpses? that thou, Ahura Mazda, takest them down to the Dakhmas? that thou, Ahura Mazda, takest them down to the unclean remains? that thou, Ahura Mazda, takest them down to the bones? and that then thou, Ahura Mazda, makest them flow back unseen? that thou, Ahura Mazda, makest them flow back to the sea Pûitika? Ahura Mazda answered:-- "It is even so as thou hast said, O righteous Zarathustra! I, Ahura Mazda, seize the waters from the sea Vouru-kasha with the wind and the clouds. I, Ahura Mazda, take them to the corpses; I, Ahura Mazda, take them down to the Dakhmas; I, Ahura Mazda, take them down to the unclean remains; I, Ahura Mazda, take them down to the bones; then I, Ahura Mazda, make them flow back unseen; I, Ahura Mazda, make them flow back to the sea Pûitika.

"This is the best, this is the fairest of all things, even as thou hast said, O pure Zarathustra!" With these words, the holy Ahura Mazda rejoiced the holy Zarathustra: "Purity is for man, next to life, the greatest good, that purity, O Zarathustra, that is in the Religion of Mazda for him who cleanses his own self with good thoughts, words, and deeds." O Maker of the material world, thou Holy One! This Law, this fiend-destroying Law of Zarathustra, by what greatness, goodness, and fairness is it great, good, and fair above all other utterances? Ahura Mazda answered:--
