"Krishna Dwaipayana Vyasa, also referred to as Vyasadeva or Vyasa, is the literary incarnation of Lord Krishna and is known as the father of all Vedic literature. Originally, the Veda, meaning “truth” or “knowledge”, was one doctrine that was passed down through oral tradition in India. Vyasadeva put the Veda into written scripture and divided it into four parts, collectively known as the Vedas. For this reason, he is also referred to as Veda Vyasa."
