"Vaisampayana said 'Then Vaka, huge as a mountain, thus broken (on Bhima's knee), died, uttering frightful yells. Terrified by these sounds, the relatives of that Rakshasa came out, O king, with their attendants. Bhima, that foremost of smiters, seeing them so terrified and deprived of reason, comforted them and made them promise (to give up cannibalism), saying, 'Do not ever again kill human beings. If ye kill men, ye will have to die even as Vaka.' Those Rakshasas hearing this speech of Bhima, said, 'So be it,' and gave, O king, the desired promise. From that day, O Bharata, the Rakshasas (of the region) were seen by the inhabitants of that town to be very peaceful towards mankind. Then Bhima, dragging the lifeless cannibal, placed him at one of the gates of the town and went away unobserved by any one. The kinsmen of Vaka, beholding him slain by the might of Bhima, became frightened and fled in different directions.
