Umananda Temple is a Shiva temple located at the Peacock Island in the middle of mghty river Brahmaputra in the heart of Guwahati city. It was built by the Ahom King Gadadhar Singha (1681–1696), who was a devout Shaivaite.
It is known as smallest inhabited riverine island in the world. Country boats that are available on the bank of Brahmaputra take the visitors to the island. The mountain on which the temple has been built is known as Bhasmacala.
Siva is said to have resided here in the form of Bhayananda. According to the Kalika Purana, in the beginning of the creation Siva sprinkled ashes (bhasma) at this place and imparted knowledge to Parvati (his consort). It is said that, when Siva was in meditation on this hillock, Kamadeva interrupted his yoga and was therefore burnt to ashes by the fire of Siva’s anger and hence the hillock got the name Bhasmacala.
This mountain is also called Bhasmakuta. The Kalika Purana states that Urvasikunda is situated here and here resides the goddess Urvasi who brings Amrit (nectar) for the enjoyment of Kamakhya and hence the island got the name Urvasi Island.
