Chandradityeshwar Mahadev Story
Demon Shambarasur defeated the Devas and took over the
heaven. All the devas went into hiding. Surya and Chandra also went into
hiding. Surya and Chandra then performed intense austerities to please Vishnu.
Bhagvan Vishnu appeared before them and asked them to go to Ujjain and offer prayers to a Shivling that is located
north of Ujjain Mahakaleshwar Temple
He told them that the fire that will emanate from the Shivling
will kill demon Shambarasur.
Chandra and Surya then offered prayers to the Shivling. In
due course of time a fire emanated from the Shivling and it annihilated demon
Shambarasur and his entire army. Thus Devas got back heaven due to the courage of Surya and Chandra
Then a voice in the heaven announced that the Shivling to
which Chandra and Surya offered prayers will be henceforth known as Chandradityeshwar
Mahadev.
