Mahaprasthanika Parva (Sanskrit: महाप्रस्थानिक पर्व), or the "Book of the Great Journey", is the seventeenth of eighteen books of the Indian epic Mahabharata. It has three chapters. It is the shortest book in the Epic.
Mahaprasthanika Parva recites the journey of the Pandavas across India and finally their ascent towards Himalayas, as they climb their way to heaven on Mount Sumeru. As they leave their kingdom, a dog befriends them and joins their long journey. On their way, Draupadi dies first. Four of the Pandava brothers also die midway. Only Yudhishthira reaches Mount Sumeru. Their conversations, and reasons for not reaching heaven are described in Mahaprasthanika Parva.
Mahaprasthanika Parva (book) has 3 adhyayas (sections, chapters) and has no secondary sub-parvas (sub-books or little books). It is the smallest book of the epic.
At the end of Mausala Parva, Vyasa advises Arjuna and his brothers to retire and renounce their kingdom as the purpose of their life has been served. Arjuna informs Yudhishthira of Vyasa's advise. Draupadi and the brothers agree.
King Yudhishthira crowns Parikshit as the king of Hastinapur, in care of Yuyutsu. In Indraprastha, Yadava prince Vajra is crowned as the king. Then they start their journey of India and the Himalayas.
As the Pandavas leave, a dog befriends them and they take him along for the journey. The Pandavas first go south, reaching the salt sea. At the coast of the salt sea, deity Agni appears and asks Arjuna to return his bow. Agni says that this bow was given to him by the gods to fight the evil on earth. Now, that purpose has been served and so Arjuna should return the bow back to the gods. Arjuna returns his bow. They turn southwest visiting sites along the way. Thereafter, they head west to see Dwaraka. They see it submerged under the sea, as described by Arjuna in Mausala Parva. The sight of a beautiful city submerged and dead, makes them depressed. They turn north, stop at Rishikesh, then cross the Himalayas.
