Zoroastrianism is one of the world's oldest religions, founded by the prophet Zoroaster in ancient Persia, around the 6th century BCE. It teaches the existence of one supreme god, Ahura Mazda, who represents truth and goodness. Followers believe in the constant battle between good and evil, and that individuals have the power to choose their path through thoughts, words, and actions. Central to Zoroastrianism is the concept of Asha, which signifies truth and order, contrasting with Druj, representing falsehood and chaos. Rituals often involve fire, symbolizing purity and the presence of Ahura Mazda. Today, Zoroastrianism has a small but dedicated following, primarily in Iran and India.
