Translation: 
Satyavrata, the saintly king of Draviḍadeśa who received spiritual knowledge at the end of the last millennium by the grace of the Supreme, later became Vaivasvata Manu, the son of Vivasvān, in the next manvantara [period of Manu]. I have received this knowledge from you. I also understand that such kings as Ikṣvāku were his sons, as you have already explained.
