In Vedic times, Indra was the supreme ruler of the gods. He was the leader of the Devas, the god of war, the god of thunder and storms, the greatest of all warriors, the strongest of all beings. He was the defender of gods and mankind against the forces of evil. He had early aspects of a sun-god, riding in a golden chariot across the heavens, but he is more often known as the god of thunder, wielding the celestial weapon Vajra, the lightening bolt. He also employs the bow, a net, and a hook in battle. He shows aspects of being a creater god, having set order to the cosmos, and since he was the one who brought water to earth, he was a fertility god as well. He also had the power to revive slain warriors who had fallen in battle.
