Accordingly king Keśidhwaja, after receiving suitable homage from Kháńd́ikya, returned to his city. Kháńd́ikya, having nominated his son Rájá, retired to the woods to accomplish his devotions, his whole mind being intent upon Govinda: there his entire thoughts being engrossed upon one only object, and being purified by practices of restraint, self-control, and the rest, he obtained absorption into the pure and perfect spirit which is termed Vishńu. Keśidhwaja also, in order to attain liberation, became averse from his own perishable works, and lived amidst objects of sense (without regarding them), and instituted religious rites without expecting therefrom any advantages to himself. Thus by pure and auspicious fruition, being cleansed from all sin, the also obtained that perfection which assuages all affliction for ever.
