The show is about the mythological story of Devi Durga and Mahishashur - how the Devi killed the Asur and became Mahishashurmardini. Shiva Purana gives an account of the origin of Durga. At the beginning of time, Lord Shiva invoked Durga, the primordial energy from his left half to create. Together they created their eternal abode, Shivaloka, also known as Kashi. Thereafter, they created Vishnu and Brahma.
