Indra is the king of the devas and Svarga in Hinduism. He is associated with the sky, lightning, weather, thunder, storms, rains, river flows, and war.  Indra is the most referred deity in the Rigveda. He is celebrated for his powers based on his status as a god of order, and as the one who killed the great evil, an asura named Vritra, who obstructed human prosperity and happiness. Indra destroys Vritra and his "deceiving forces", and thereby brings rain and sunshine as the saviour of mankind.
