varadānena śukrasya na śakyaṃ vaktumuttaram || 23 ||

"The people then said, 'True it is, O king, that, that son who is accomplished and who seeketh the good of his parents, deserveth prosperity even if he be the youngest. Therefore, doth Puru, who hath done the good, deserve the crown. And as Sukra himself hath commanded it, we have nothing to say to it.'
