Mahabharata was written by Sage Vyasa and helped by Lord Ganesha in writing the Mahabharata and contains the story of the Kauravas and Pandavas and the battle of succession to throne. Bhavat Geeta was recited in this and considered to be very sacred to Hindus. I have been told the stories of MahaBharata from my very early age and give them here in very simple form so that is easy for anybody to read and understand without going through all the big descriptions and explanations.
