In Zoroastrian mythology, the celestial beings that serve as angels are called Ahuras and Yazatas. The Ahuras represent divine entities embodying order and truth, while the Yazatas are spirits of nature and lesser divinities. These beings play essential roles in maintaining the cosmic order, reflecting the dualistic nature of Zoroastrianism, which emphasizes the eternal battle between Ahura Mazda (the supreme god) and the forces of chaos.
