When Zarathustra was engaged in singing the Dathas and attending the sacred fire, Homa appeared before him in resplendently supernatural guise and explained “I am Homa, whom thou shouldst worship as the sages and prophets of old have done.” “Tell me,” replied Zarathustra, “who was it that first worshipped thee by extracting thy juice from the plant?” “The first,” said Homa, “was Vivan-Ghvant whose reward was the birth of his august and renowned son, Yima, (6) the king, in whose reign there was neither death, nor scorching heat, nor benumbing cold, but when fulness of life, perfection of happiness, and unfailing justice prevailed. The second to worship me,” said Homa, “was Athwya, the blessed one, and to him as a reward was born Thraetaona, who slew the three-mouthed, three-tailed, six-eyed, thousand-scaled dragon that wrought such dire havoc in the world. The third to worship me was Thrita, to whom, in recompense, were born two sons of illustrious name, one great as ruler of men, and the other a brave warrior who slew the man-and-horse-swallowing dragon. The fourth was thine own distinguished father, Pourushasha, and the reward that he received was to have thee, O great prophet of men, for his son.” On hearing which Zarathustra immediately set about walking around the sacred fire singing lustily the praises of the god Homa, whom his father had worshipped. “It is Homa,” sang the prophet, “that gives men knowledge of things new and old. Even men buried under a weight of book-lore receive from him inspiration and perception of truth that no books can impart. It is Homa that gives kind and wealthy husbands to unwed maidens; that fills the sky with clouds and refreshes the ground with life-giving showers, causing the plants to grow on the lofty mountains on whose brow thine own sacred plant (asclepias) flourishes.”
CHAPTER 12. [Profession of faith on the part of the new convert, uttered by the ancient Iranians on their giving up the worship of Daevas and the nomad life, and on their being received into the religious community established by Zarathustra.]
Now cease I to be a Daeva worshipper and make profession of the religion of Ahura-Mazda, proclaimed by Zarathustra. I ascribe all good things everywhere to Ahura-Mazda, the true, shining and holy one. I will never more molest Mazdaists. I will forsake the Daevas, the false and wicked originators of all the mischief in the universe. I forsake also all Daeva like beings, witches, wizards, and the like. I belong to the Mazdaist religion, and will support it to my dying day. There is no joy of virtue but has come from Ahura-Mazda.
CHAPTER 19. The importance and value of the Ahuna-Vairya prayer, said Zarathustra to Ahura-Mazda “O holiest and best of beings, what words taughtest thou me before the world was, or human life began its history?” “It was,” responded the supreme being, “the Ahuna-Vairya prayer. Whoever, O Zarathustra, recites this prayer or intones it, or even whispers it under his breath, I will carry him safely across the bridge which leads to paradise. But whoever cuts this prayer short by a half, a third, a fourth, or by any quantity, his soul shall I keep out of paradise and it shall wander in sorrow for ever.”
