He was present along with Nārada at the sacrificial ceremony of Mahārāja Janamejaya, son of Mahārāja Parīkṣit. In this sacrifice all the snakes of the world were to be killed. Parvata Muni and Nārada Muni are called Gandharvas also because they can travel in the air singing the glories of the Lord. Since they can travel in the air, they observed Draupadī's svayaṁvara ceremony (selecting of her own husband) from the air. Like Nārada Muni, Parvata Muni also used to visit the royal assembly in the heaven of King Indra. As a Gandharva, sometimes he visited the royal assembly of Kuvera, one of the important demigods. Both Nārada and Parvata were once in trouble with the daughter of Mahārāja Sṛñjaya. Mahārāja Sṛñjaya got the benediction of a son by Parvata Muni.
