After the end of the Mahabharata war, the Pandavs heard the sound of laughter. When they went near the source of sound, they could see Barbarika’s head. Barbarika was none other than grandson of Bhima and Hidimba. When he was a child he was taught by his grandmother Hidimba that one would be liberated even if he is killed by Krishna. This lesson was engraved in his mind deeply and to fulfill this mission he perfomed austerities for many years and obtained powerful weapons from various demi-gods. When the Mahabharat war was about to begin Barbarika decided to take the side of Kauravas. When Krishna did not approve of this, he told Krishna that he would kill the Pandavas at once and was about to shoot a weapon at them. Immediately he was beheaded by Lord’s Sudarshan chakra and his wish of being killed by Krishna was fulfilled by the Lord. Then Barbarika offered prayers to the Lord and requested Krishna to allow him to watch the pastimes of the Lord in Mahabharat war. The Lord granted him spiritual vision. After watching all the pastimes of the Lord, Barbarika was lauging in ecstacy recollecting the same. When the Pandavas heard this from Barbarika, they were eager to know who fought more bravely in the war. Barbarika replied – “In reality, NO ONE FOUGHT. Every where it was only sudarshan chakra which was moving around actively causing Bhismadev, Dronacaraya, Karna, Jayadrath and all the warriors to fall down.”
