He, O king, for whom thou grievest now lies within a lake whose waters have been solidified by him!" Hearing these agreeable words of Bhimasena, O monarch, Kunti's son, Ajatasatru, became, with all his brothers, filled with joy. Having learnt that the mighty bowman Duryodhana had penetrated into the waters of a lake, the king proceeded thither with great speed, with Janardana at his head. Then a tumultuous noise arose, O monarch, from among the Pandavas and the Pancalas all of whom were filled with joy. The warriors uttered leonine roars, O bull of Bharata's race, and shouted loudly. All the Kshatriyas, O king, proceeded with great speed towards that lake called Dvaipayana. The rejoicing Somakas all around loudly and repeatedly exclaimed, "The sinful son of Dhritarashtra has been found!" The noise made by the cars of those impetuous warriors who proceeded with great speed, became very loud, O monarch, and touched the heavens. Although their animals were tired, all of them still proceeded with speed behind king Yudhishthira who was bent upon finding out Duryodhana. Arjuna, and Bhimasena, and the two sons of Madri by Pandu, and the Pancala prince Dhrishtadyumna, and the unvanquished Shikhandi, and Uttamaujas, and Yudhamanyu, and the mighty car-warrior Satyaki, and the (five) sons of Draupadi, and those amongst the Pancalas, O king, that were yet alive, and all the Pandavas, and all their elephants, and foot-soldiers by hundreds upon hundreds, all proceeded with Yudhishthira. Possessed of great valour, king Yudhishthira the just, O monarch, arrived at the lake known by the name of Dvaipayana within which Duryodhana then was. Wide as the ocean itself, its aspect was agreeable and its waters were cool and transparent. Solidifying the waters by means of his power of illusion, by, indeed, a wonderful method, thy son Duryodhana, O Bharata, happened to be within that lake.
