WHAT ? - IF I DON"T UNDERSTAND !

I Liked the Story told to me by Sj. Arun Miyra , next-door neighbor, It was told to him by his school-teacher and the real author or source is not known. Yet it has a great message :
A king ( let's say "once upon a time) Declared a great reward to any one in his kingdom , if one could make him understand that 2+2 = 4.
The Queen was furious and scolded the King for risking on such a bet, as it was so easy to make anyone understand that 2+2 is always equal to 4.

The king smiled and replied -' why do you worry so much lady ! If I refuse to nderstand it , where is there any one , who can force me to understand ?

The moral is interesting and Universal even for psychology or Spirituality !
