This is one of the supreme moments in the life of Krishna and is only epitomized by his monumental failure on this very moment. In this moment of his life, Krishna reaches a monumental and divine heights (other moment being discourse of Geeta, of course). He became famous for rising so high in life on such occasions, but tragically, although he became known, respected and feared, he failed on his primary objective, that was to avert the disastrous war. Krishna used all his knowledge, his powers, his skills of persuasion to avert the war in this episode of Mahabharat. But, all his efforts proved to be utter failure in changing the heart of Duryodhan and averting the disaster.
