Vedavyas

Vyasa is the legendary author of the Mahabharata, Vedas and Puranas, some of the most important works in the Hindu tradition. He is also called Veda Vyasa ("the one who classified the Vedas") or Krishna Dvaipayana (referring to his dark complexion and birthplace). Vyasa is traditionally known as the chronicler of this epic and also features as an important character in Mahabharata, Vyasa asks Ganesha to assist him in writing the text. Ganesha imposes a precondition that he would do so only if Vyasa would narrate the story without a pause. Vyasa set a counter-condition that Ganesha understand the verses first before transcribing them. Thus Vyasa narrated the entire Mahabharata and all the Upanishads and the 18 Puranas, while Lord Ganesha wrote.
