The Pastimes of Supreme Lord Krishna are described in the 19th chapter of the Tenth Canto of Srimad Bhagvatam, where the cow's and cowherd boys of Varja became trapped in a blazing fire in the Munja Forest.  When the Flames of the Forest fire threatened to engulf the cowherd boys, they appealed to Sri Krishna to rescue them.  Krishna requested them to close their eyes,and once they had closed their eyes.  He opened his mouth and swallowed the Fire.  Our only refuge in this scorching fire of material existence is the Supreme Lord Nandnandan Sri Krishna.  we are deluded if we think that we are ever safe without Him.  Simply by trusting him, as demonstrated by the cowherd boys, shutting their eyes to imminent danger, his devotees are rescued from the relentless flames of mundane world.
