The Beauty of Gentleness

The North Wind and the Sun had an argument one day.  They were disputing which was the stronger. Suddenly they saw a traveler coming down the road, and the Sun said, "I see a way to decide our dispute. Whichever of us can cause that traveler to take off his cloak shall be regarded as the stronger. You begin."

So the Sun retired behind a cloud, and the Wind began to blow as hard as it could upon the traveler. But the harder he blew the more closely did the traveler wrap his cloak round him.  The wind sent rain, even hail.  The traveler clung even more desperately to his cloak.  At last the Wind had to give up in despair.

Then the Sun came out and shone in all his glory upon the traveler. 
Quite soon the man removed his cloak from the warmth of the day.
