(or Vedavyasa)
Vyasa (arranger or compiler) is the sage or RISHI who compiled all the VEDAS. He did not “write”them—they are eternal MANTRAS that are received by different rishis in different eras, as the world is re-created. He is identified with the Vyasa who recited the ancient MAHABHARATA story to the god GANESHA, who wrote it down. In the Mahabharata Vyasa is also called Krishna Dvaipayana. The Vedavyasa who composed the most commonly consulted Sanskrit commentary on the YOGA SUTRA is also considered to be the same person.
