pratyakṣaṃ bhūpatis tasyāḥ surucyā nābhyanandata
praṇayenāgataṃ putram utsaṅgārohaṇotsukam //

PARÁŚARA continued.--I mentioned to you, that the Manu Swáyambhuva had two heroic and pious sons, Priyavrata and Uttánapáda. Of these two, the latter had a son whom he dearly loved, Uttama, by his favourite wife Suruchi. By his queen, named Suníti, to whom he was less attached, he also had a son, called Dhruva. Observing his brother Uttama on the lap of his father, as he was seated upon his throne, Dhruva was desirous of ascending to the same place; but as Suruchi was present, the Rája did not gratify the desire of his son, respectfully wishing to be taken on his father's knee. Beholding the child of her rival thus anxious to be placed on his father's lap, and her own son already seated there, Suruchi thus addressed the boy: "Why, child, do you vainly indulge in such presumptuous hopes? You are born from a different mother, and are no son of mine, that you should aspire inconsiderately to a station fit for the excellent Uttama alone. It is true you are the son of the Rája, but I have not given you birth. This regal throne, the seat of the king of kings, is suited to my son only; why should you aspire to its occupation? why idly cherish such lofty ambition, as if you were my son? do you forget that you are but the offspring of Suníti."
