kausalye dharmatantraṃ yadbravīmi tvāṃ nibodha me |
bharatānāṃ samucchedo vyaktaṃ madbhāgyasaṃkṣayāt || 45 ||

"Vaisampayana continued, 'Having spoken thus unto Satyavati, Vyasa of great energy addressed her and said, 'Let the princess of Kosala clad in clean attire and checked with ornaments wait for me in her bed-chamber.' Saying this, the Rishi disappeared, Satyavati then went to her daughter-in-law and seeing her in private spoke to her these words of beneficial and virtuous import, 'O princess of Kosala, listen to what I say. It is consistent with virtue. The dynasty of the Bharatas hath become extinct from my misfortune. Beholding my affliction and the extinction of his paternal line, the wise Bhishma, impelled also by the desire of perpetuating our race, hath made me a suggestion, which suggestion, however, for its accomplishment is dependent on thee. Accomplish it, O daughter, and restore the lost line of the Bharatas. O thou of fair hips, bring thou forth a child equal in splendour unto the chief of the celestials. He shall bear the onerous burden of this our hereditary kingdom.'
