In the Vedas, Indra Dev is considered to be the King of Devas (all gods) and the one who lives in Swarga (heaven). The word Indra comes from ‘Indriyan’, the senses. It is said that Indra is not the name of a person, but a position, a chair. Indra is the God of lightning, thunder, storms, rains and river flows. He is known as the one who kills Vrita (Asura), who is the personification of drought.
