Once two frogs had fallen into a milk pot, and were drowning. After struggling to keep afloat for some time, one frog gave up hope and drowned. The other frog, however, was more determined and he kicked and kicked, despite the hopeless situation. But due to all this kicking the milk started to churn and soon a hard lump of butter was formed. By standing on this, the frog was able to jump out of the bucket.
MORAL: Be determined for Krishna.
