Tāmasa, the brother of the third Manu, was the fourth Manu, and he had ten sons, including Pṛthu, Khyāti, Nara and Ketu. During his reign, the Satyakas, Haris, Vīras and others were demigods, the seven great saints were headed by Jyotirdhāma, and Triśikha became Indra. Harimedhā begot a son named Hari in the womb of his wife Hariṇī. This Hari, an incarnation of God, saved the devotee Gajendra. This incident is described as gajendra-mokṣaṇa. At the end of this chapter, Parīkṣit Mahārāja particularly asks about this incident.
