In order to enhance their imperial claims, the Paramaras promoted several legends associating Bhoja with the ancient legendary kings. For example, in Simhasana Dvatrimsika (popularly known as Singhasan Battisi), Bhoja finds a throne of Vikramaditya, and each of the 32 divine figurines attached to the throne tell him a story about Vikramaditya. A Bhavishya Purana legend describes Bhoja as a descendant of Vikramaditya and Shalivahana. According to this legend, the mleccha (foreign) influence had corrupted Indian culture by the time of Bhoja's ascension. Bhoja marched up to the banks of the Indus river, and defeated several mleccha kings. The poet Kalidasa, who accompanied him, magically turned into ashes a mleccha named Mahamada, whose followers came to be known as Muslim (The character Mahamada is based on Muhammad possibly combined with Mahmud of Ghazni). After returning to his capital, Bhoja established Sanskrit language among the top three varnas and Prakrit language among the Shudras. During his 50-year reign, Aryavarta (the land between the Himalayas and the Vindhyas) became a blessed land where the varna system was established. On the other hand, caste mixture took place beyond the Vindhyas (that is, in South India). Again, this is an imaginary account not supported by any historical evidence.
