Ādivaṃśāvataraṇa Parva: The Birth of Veda Vyasa
The fifty-seventh adhyāya of the Ādi-parva starts with the story of King Uparicara. Some scholars opine that this is the real beginning of the Bhārata epic because Uparicara’s daughter Matysagandhī (also called Satyvavatī, Kālī, Yojanagandhī, and Gandhavatī) is the mother of Vyāsa, who is the ancestor of both the Kauravas and the Pāṇḍavas. This section narrates the incidents that led to her becoming the daughter of a fisherman and the birth of Vyāsa through Parāśara; several fantastic explanations have been given to support these episodes.
