What is Zoroastrianism?

Long ago, Persians worshipped Mithras, the god of light, truth and justice. Around 600 BC, a Persian prophet named Zarathushtra founded a religion called Zoroastrianism. Persians in parts of Iran and India still follow this religion. He preached that there was only one god, Ahura Mazda Ahura meaning ‘lord’ and Mazda meaning, ‘wise’. The basic scripture of Zoroastrianism is a set of five poetic songs called ‘gathas’, composed by Zarathustra himself.
