Its funny how origin myths were being cooked up as recently as british period and today many people take such myths and fabrications as eternal truths.
>Bharatendu Harishchandra (1850-1885), a renowned Agrawal author and poet, compiled the legend of Maharaja Agrasen in his 1871 essay Agarwalon ki Utpatti ("Origins of Agrawals and Agrahari"). >Bhartendu is not clear about his sources, stating that he compiled the legend from "tradition" and "ancient writings", naming one of these texts as Sri Mahalakshmi Vrat Ki Katha ("The Story of the Fast for Goddess Mahalakshmi"). He claimed to have found this text in a "later" part of the Bhavishya Purana, which exists in several recensions. However, subsequent researchers were UNSUCCESSFUL in tracing this text in any published version of the "Bhavishya Purana.[12] In 1976, the Agrawal historian Satyaketu Vidyalankar published a copy of the Mahalakshmi Vrat Ki Katha in his Agrwal Jati Ka Prachin Itihas ("Ancient History of the Agrawal caste"). He states that he had found this copy in the personal library of Bharatendu Harishchandra; some academics note that this copy DOES NOT contain any clue about its origin.
