"Then Vidura, having learnt that Draupadi had been won by the Pandavas and that the sons of Dhritarashtra had come back (to Hastinapura) in shame, their pride humiliated, became filled with joy. And, O king, approaching Dhritarashtra, Kshattri said, 'The Kurus are prospering by good luck!' Hearing those words of Vidura, the son of Vichitravirya, wondering, said in great glee, 'What good luck, O Vidura! What good luck!' From ignorance, the blind monarch understood that his eldest son Duryodhana had been chosen by Drupada's daughter as her lord. And the king immediately ordered various ornaments to be made for Draupadi. And he commanded that both Draupadi and his son Duryodhana should be brought with pomp to Hastinapura. It was then that Vidura told the monarch that Draupadi had chosen the Pandavas for her lords, and that those heroes were all alive and at peace, and that they had been received with great respect by king Drupada. And he also informed Dhritarashtra that the Pandavas had been united with the many relatives and friends of Drupada, each owning large armies, and with many others who had come to that self-choice.
