The great Bharata, Bharata is the ancient name of India, composed by Vyasa, written down by Ganesha (the opening image of the website shows this scene), had 8,800 verses and was called Jaya. Now it has 100,000 verses, because storytellers added stories. After Jaya it was called Vijaya, then Bharata and afterwards Mahabharata.
The Bharata was weighed against the Veda and it weighed heavier. So it became the Mahabharata. In addition to the core story, the work contains the subsequently added Bhagavad Gita, the spiritual discourse between Krishna and Arjuna. Countless myths, parables, didactic plays and wisdom are also woven in. It is said: What is not in the Mahabharata is nowhere, what is in the Mahabharata is everywhere. The 100,000 verses make it the most extensive work ever written, written in expansive, flowery, epic language.
