The Mahabharata writing is the essence of the Indian Hindu Culture. In its original Sanskrit, it is the longest epic story ever composed. Vyasa agreed to let Ganesh write his epic.
Ganesh had to agree to understand every verse he was going to write for the Vyasa. After every verse the Ganesh had to think of the meaning before Vyasa would continue on to another verse. Ganesh used his broken tusk to write the epic. There is a lesson from the epic and it should be read carefully and understood.
