Story of Indreshwar Mahadev form of Shiva in Ujjain
There was a pious prince named Kushdwaj. He was the son of Prajapati Twashta. One day for some reason, Indra, the king of Devas, killed Kushdwaj. An angry Prajapati Twashta, removed a strand of hair and threw it into fire. From it appeared Vritasur, who defeated Indra and made him a prisoner.
Vritasura now ruled heaven.
Brihaspati, the guru of Devas, secured the release of Indra.
Indra asked his Guru how he could get back his position as the king of Devas.
Brihaspati asked Indra to worship a particular Shivling located in the southern direction at Mahakaal Van (present day Ujjain).
Indra performed intense austerities and pleased Shiva by performing puja to the Shivling. Shiva then blessed Indra with powers to overcome Vritasura.
Indra then defeated Vritasura and regained his position as the King of Devas.
As Indra offered prayers to the Shivling, it came to be known as Indreshwar.
It is believed that those who offer prayers to Indreshwar Shivling will attain heaven after death.
