Bhima Slain by the Yaksha
With Arjuna also dead by the lake, Yudhishthira sends Bhima. Bhima finds his four brothers lying dead and suspects yakshas or rakshasas. He resolves to fight — but decides to drink first, ignores the yaksha's warning, and collapses dead beside them.
Yudhishthira was alone now. He spoke to Bhimasena.
"O descendant of the Bharata lineage! Nakula, Sahadeva and the unvanquished Bibhatsu have been gone for a long time, having gone to fetch water. Go and fetch them and bring the water."
Bhima left in the same direction where his brothers had fallen. He found them — all four, tigers among men, lying dead on the ground.
He was distressed. He was oppressed by thirst. But his mind worked. He thought: this must have been the work of yakshas or rakshasas. He thought: I will certainly have to fight today. But let me drink the water first.
He rushed toward the water.
The yaksha said: "O son! Do not be foolish enough to do this. I have obtained possession of this earlier. O Kounteya! Answer my question. You can then drink it and take it."
Bhima ignored the words of the infinitely energetic yaksha. He drank.
He collapsed and fell down.
All four Pandava brothers now lay dead by the lake. Only Yudhishthira remained. Aranyaka Parva, Chapter 593
