Zoroastrianism is one of the world's oldest monotheistic religions, founded by the prophet Zoroaster in ancient Persia, around the 6th century BCE. The religion centers on the worship of Ahura Mazda, the supreme god, who represents truth and goodness. Zoroastrians believe in the duality of good and evil, emphasizing the importance of individual choice in the battle between these forces. The sacred texts of Zoroastrianism are known as the Avesta, which includes hymns, rituals, and teachings. Followers practice rituals such as the Navjote, a coming-of-age ceremony, and celebrate festivals like Nowruz, the Persian New Year, which symbolizes renewal and the triumph of light over darkness.
