His father, Kritavîrya will worship the thousand-rayed Sun according to the Vedic hymns with fasts and vows, in order to ward off the sage's curse, so that the son may not die in infancy. He will then come to know of the rituals of this particular ablution from the God Sun, who will relate to the king the ways of the ordinance that would wash off all sins and allay all misfortunes.—11-12.
