One day during the exile, the Pandavas became extremely thirsty and asked Nakula, the youngest of Pandavas, to get some water from a nearby pond. When Nakula did not return one by one the Pandavas went looking for the other and finally Yudhisthira, the eldest, discovers the four brothers lying dead nearby the pond. Suddenly, Yudhisthira hears the voice of Yaksha who warns him not to drink the water from the pond before he has answered his questions; otherwise, he would also be dead. Yudhishtira agrees to answer the question of Yaksha.
