Iv'e heard that the eyes are the windows to the soul. And the soul lives in the heart.
And when the heart stop beating ,your dead. And the spirit that lives inside ones soul is gone from the presence of the living forever.
  Dont abuse it
Don't burn it
Don't sell it
Don't give it away
Protect the heart,
live by it,
listen to it ,
share it.
We only have 1 and when it stops everything else stops with it.....
