Vaisampayana continued, "After this, all of them went to king Yudhishthira the just. And going unto the king, they represented unto him everything about Duryodhana's conduct. And Ajatasatru, hearing everything that the Gandharvas had said, liberated all the Kauravas and applauded the Gandharvas. And the king said, 'Fortunate it is for us that though gifted with great strength, ye did not yet slay the wicked son of Dhritarashtra along with all counsellors and relatives. This, O sir, hath been an act of great kindness done to me by the Gandharvas. The honour also of my family is saved by liberating this wicked wight. I am glad at seeing you all. Command me what I am to do for you. And having obtained all you wish, return ye soon whence ye came!'
