Devas appealed to Indira to protect them from the atrocities of demon Vruddhasura with the might of the boon he obtained from Lord Brahmma.
Indira fought the demon and killed him and incurred the evil effect of the killing. He also lost his kingship of the Devas. As advised by his Guru, Jupiter, he came down to earth to worship Lord Shiva for remedy.
He came to this jungle region-Aaranyam, found a Swayambulinga and performed pujas. Pleased with his devotion, Lord appeared before Indira and said that the effects of both good and bad deeds had to be experienced by all. Lord stayed here then as Aaranyeswarar.
