27.9

nādhyagacchata tāṃ nārīṃ yasyām evaṃvidhaḥ sutaḥ
bhavet sarvaguṇopeto rājño devāvṛdhasya ca |
jāyet tasmāt svayaṃ hanta bhavāmy asya sahavratā //

She could not find that woman in whom such a son / could be born to King Devāvṛdha, endowed with all virtues. / “Therefore, alas, I myself shall become his companion in vows.”
