The Mahabharata is one of the two major Sanskrit epics of ancient India. It is an epic narrative of the Kurukshetra War and the fates of the Kauravas and the Pandava princes as well as containing philosophical and devotional material, such as a discussion of the four goals of life.
Here we have Mahaprasthanika Parva, the seventeenth, narrating the story of the journey of Yudhisthira and his brothers across the country and finally their ascent of the Himalayas where all Pandava except Yudhisthira falls.
Vyasa is a revered figure in Hindu traditions. He is a kala-Avatar or part-incarnation of God Vishnu. Vyasa is sometimes conflated by some Vaishnavas with Badarayana, the compiler of the Vedanta Sutras and considered to be one of the seven Chiranjivins. He is also the fourth member of the Rishi Parampara of the Advaita Guru Parampara of which Adi Shankara is the chief proponent.
