Narakasura used several divine weapons against Lord Krishna, but Krishna easily neutralized all those weapons. Narakasura used the Brahmastra against Lord Krishna, but Lord Krishna neutralized it with his own Brahmastra. Narakasura used the Agneyastra against Lord Krishna, but Lord Krishna neutralized it with the Varunastra. Narakasura used the Nagapasha against Lord Krishna, but Lord Krishna neutralized it with the Garudastra. In desperation, Narakasura launched the Vaishnavastra on Lord Krishna, but Lord Krishna neutralized it with another Vaishnavastra. At last, when Narakasura tried to kill Lord Krishna with a trident, Lord Krishna beheaded him with his Sudarshana Chakra (discus).
