Story of Siddheshwar Mahadev form of Shiva in Ujjain
Ekachitra did intense penance for several years but he was not able to achieve anything. He became angry and started criticizing gods and their worship. He soon turned into a nonbeliever.
Then one day Ekachitra had a dream. In it he was asked to go to Mahakaal Vana (present day Ujjain) and offer prayers to a particular Shivling.
Ekachitra discovered the Shivling in Mahakaal Vana and offered prayers. Soon he attained various Siddhis. From that day onwards, the Shivling came to be known as Siddheshwar Mahadev.
