Kitap 23
6.33
When Zoroaster had boldly made his way into the unknown regions of Upper India, he reached a wooded wilderness, whose calm silence the lofty intellects of the Brahmins control. From their teaching he learned as much as he could grasp of the laws regulating the movements of the earth and the stars, and of the pure sacrificial rites. Of what he had learned he communicated something to the understanding of the Magi, which they, along with the art of divining the future, hand on from generation to generation to later times.
6.34
From that time on for many ages down to the present a large class of men of one and the same descent have devoted themselves to the service of the gods.Their priesthood was hereditary, handed on from father to son. The Magi also say (if it is right to believe them) that they guard on ever-burning braziers a fire sent down from heaven in their country, and that a small portion of it, as a good omen, used to be carried before the Asiatic kings.
