Vyasa is depicted as the spiritual preceptor of five Brahmins who learned from him the Vedas and the MBh, and whom he instructed in religion . He also gave spiritual counsel to members of the Bharat family, both Pandavas and Kauravas , exercising control over their lives. That he was their spiritual preceptor as well as their concerned elder is particularly evident in the case of Pandavas, in whose lives the major events were supervised by Vyasa.
In Mahabharata there is a mention of the Pandavas going to Heaven and Kauravas to Hell .
Now seeing the armies of the Pandavas arrayed in battle formation, King Duryodhana, approaching his teacher , spoke these words: [Duryodhana said:] Behold these mighty warriors of the sons of Pandu, O Revered Teacher, Arrayed in battle formation by the son of Drupada, your own skillful student.
