Actor Nitish Bharadwaj says his show "Vishnu Puran" brings out theories and principles that give a deep insight into ancient Indian knowledge pool. Based on an ancient collection of stories and scriptures, the 2000 show is set to return to the small screen. Nitish plays Lord Vishnu in the show, which aims to impart interesting life lessons."'Vishnu Puran' as a show brings out theories and principles that give a deep insight into ancient Indian knowledge pool. Prior to taking up this show, I had read the manuscripts of Vishnu Puran and immediately recollected the Theory of Evolution put forth in the 19th century by the naturalist, Charles Darwin. While his theories might have been true and perceived the first of its form in the West, from the perspective of India's age-old heritage and culture, I personally believe that Maharshi Ved Vyas was the first anthropologist author to address and establish human evolution via the Vishnu Puran manuscript," said Nitish.
