Bhima and Arjuna once had an argument as to who was the fiercest in the Kurukshetra war in the Mahabharat. Both claimed that they inflicted the greatest damage on the Kauravas. None of the Pandavas or those who participated or witnessed the battle was able to decide who was the fiercest.
Finally, Bhima and Arjuna decided to ask Barbareek, the bodiless head, who witnessed the Kurukshetra war from a hill.
When asked who was the fiercest in the battle and who inflicted the maximum damage on the Kaurava army, Barbareek answer was spectacular.
Barbareek said that he did not see Bhima or Arjuna, he only witnessed Vishnu’s Sudharshana Chakra (discus) cutting the heads of Adharmic kings and people on earth. The earth then took the form of Goddess Kali and drank the blood of the greedy and power hungry kings.
