Dillipa in
Hindu mythology is said to have been one of the most righteous and chivalrous emperors that the
Solar Dynasty had ever produced. He was not blessed with a child for a long time and that caused great worry in his mind. In the matter of begetting an heir, he took the advice of Sage
Vasishta. The sage divined his condition and told him that, once on the way back to earth after fighting a war on the side of the Gods, Dileepa failed to notice the divine cow
Kamadhenu on his way and passed without paying his respects to her. Thereby he incurred the anger of the cow, who cursed the king to go childless. To negate the ill-effects of the curse, the King was advised to worship the divine cow
Nandini who was the daughter of
Kamadhenu, and thereby to earn her goodwill.
