Karna was lying on the battlefield gasping for breath in his last moments.
Assuming a tone of revulsion, Krishna said: "What is it you suggest? Do you expect me to break your teeth and take the gold from them? How can I do such a wicked deed? I am a Brahmin." Immediately, Karna picked up a stone nearby, knocked out his teeth and offered them to the "Brahmin".
Krishna in his guise as Brahmin wanted to test Karna further. "What? Are you giving me as gift teeth dripping with blood? I cannot accept this. I am leaving", he said. Karna pleaded: "Swami, please wait for a moment." Even while he was unable to move, Karna took out his arrow and aimed it at the sky. Immediately rain dropped from the clouds. Cleaning the teeth with the rainwater, Karna offered the teeth with both his hands.
Krishna then revealed his original form. Karna asked: "Who are you, Sir"? Krishna said: "I am Krishna. I admire your spirit of sacrifice. In any circumstance you have never given up your spirit of sacrifice. Ask me what you want." Beholding Krishna's beauteous form, Karna said with folded hands: "Krishna! To have the vision of the Lord before one's passing is the goal of human existence. You came to me and blessed me with your form. This is enough for me. I offer my salutations to you." In this way, Karna stayed DAANVEER till the very end.
