“Lomasa said, ‘That same king, of a powerful bow, standing at the head of the surrounding, (i.e., the occupant of an imperial throne) of a powerful car, (i.e., possessing every great fighting power) became the delight of the eyes and the soul of all the world. And he of the powerful arm came to learn how his forefathers had met an awful end from Kapila of mighty soul, and how they had been unable to attain the region of gods.

In plain words: The sage Lomasa tells of a great and much-loved king, Bhagiratha. The king learned that his ancestors had died a terrible death through the great sage Kapila and could not reach heaven.
