tathāpi duḥkhaṃ na bhavān kartumarhasi putraka /
yasya yāvatsa tenaiva svena tuṣyati mānavaḥ //

The boy, having heard the speech of his step-mother, quitted his father, and repaired in a passion to the apartment of his own mother; who, beholding him vexed, took him upon her lap, and, gently smiling, asked him what was the cause of his anger, who had displeased him, and if any one, forgetting the respect due to his father, had behaved ill to him. Dhruva, in reply, repeated to her all that the arrogant Suruchi had said to him in the presence of the king. Deeply distressed by the narrative of the boy, the humble Suníti, her eyes dimmed with tears, sighed, and said, "Suruchi has rightly spoken; thine, child, is an unhappy fate: those who are born to fortune are not liable to the insults of their rivals. Yet be not afflicted, my child, for who shall efface what thou hast formerly done, or shall assign to thee what thou hast left undone. The regal throne, the umbrella of royalty, horses and elephants, are his whose virtues have deserved them: remember this, my son, and be consoled. That the king favours Suruchi is the reward of her merits in a former existence. The name of wife alone belongs to such as I, who have not equal merit. Her son is the progeny of accumulated piety, and is born as Uttama: mine has been born as Dhruva, of inferior moral worth. Therefore, my son, it is not proper for you to grieve; a wise man will be contented with that degree which appertains to him: but if you continue to feel hurt at the words of Suruchi, endeavour to augment that religious merit which bestows all good; be amiable, be pious, be friendly, be assiduous in benevolence to all living creatures; for prosperity descends upon modest worth as water flows towards low ground."
