ikṣvākuvaṃśaṃ vakṣyāmi śṛṇudhvamṛṣisattamāḥ //

Ṛiṣis! now listen, I am going to relate to you the family of Ikṣvâku :—

Kakudmî. He had also a daughter, named Revatî, who was the wife of Balarâma. Karuṣa begot innumerable progeny, who were known by the name of Kâruṣa. Priṣadhra became śudra by the curse of his preceptor for killing a cow.—23-24.
