Thereupon, the invisible Yaksha said, ‘What need of all this trouble, O son of Pritha? Do thou drink only after answering my questions! If thou drink, however, without answering my questions, thou shalt die immediately after.’ Thus addressed, Pritha’s son Dhananjaya capable of drawing the bow with his left hand as well, disregarding those words, drank of the water, and immediately after dropped down dead. And (seeing Dhananjaya’s delay) Kunti’s son Yudhishthira addressed Bhimasena, saying, ‘O represser of foes, it is a long while that Nakula and Sahadeva and Vibhatsu have gone to fetch water, and they have not come yet, O Bharata! Good betide thee! Do thou bring them back, together with water!’ Thereupon saying, ‘So be it,’ Bhimasena set out for that place where those tigers among men, his brothers, lay dead. And beholding them, Bhima afflicted though he was with thirst, was exceedingly distressed. And that mighty armed hero thought all that to have been the act of some Yaksha or Rakshasa. And Pritha’s son Vrikodara thought, ‘I shall surely have to fight today. Let me, therefore, first appease my thirst.’ Then that bull of the Bharata race rushed forward with the intention of drinking. Thereupon the Yaksha said, ‘O child, do not commit this rash act! This lake hath already been in my possession. Do thou first answer my questions, and then drink and take away as much water as thou requirest!’”
