According to later Zoroastrian tradition, when Zoroaster was 30 years old, he went into the Daiti river to draw water for a Haoma ceremony; when he emerged, he received a vision of Vohu Manah. After this, Vohu Manah took him to the other six Amesha Spentas, where he received the completion of his vision. This vision radically transformed his view of the world, and he tried to teach this view to others. Zoroaster believed in one supreme creator deity and acknowledged this creator's emanations (Amesha Spenta) and other divinities which he called Ahuras (Yazata). Some of the deities of the old religion, the "Daevas" ("Devas" in Sanskrit), appeared to delight in war and strife and were condemned as evil workers of Angra Mainyu by Zoroaster.
