Indra (/ˈɪndrə/, Sanskrit: इन्द्र) is the leader of the Devas and the lord of Svargaloka or a level of Heaven in Hinduism. He is the deva of rain and thunderstorms. He wields a lightning thunderbolt known as vajra and rides on a white elephant known as Airavata. His horse's name is Uchchaihshrava. Indra is the most important deity worshiped by the Rigvedic tribes and is the son of Dyaus and the goddess Savasi. His home is situated on Mount Meru in the heavens. He is celebrated as a demiurge who pushes up the sky, releases Ushas (dawn) from the Vala cave, and slays Vṛtra; both latter actions are central to the Soma sacrifice. He is associated with Vajrapani - the Chief Dharmapala. On the other hand, he also commits many kinds of mischief (kilbiṣa) for which he is sometimes punished. In the Puranas, Indra is bestowed with a heroic and almost brash and amorous character at times, even as his reputation and role diminished in later Hinduism with the rise of the Trimurti.
