He is best known as the author of the Mahabharata, one of the two most important epics of Hinduism. He is also credited as the traditional compiler of the Vedas, as well as the writer of other important works including the Puranas.

Throughout the epic, Vyasa appears occasionally helping the Kuru kingdom. His spiritual career includes compiling many texts and spreading the knowledge through his disciples. The festival of Guru Purnima is dedicated to him. It is also known as Vyasa Purnima, the day believed to be both of his birth and when he divided the Vedas.
