It happened that a Dog had got a piece of meat and was
carrying it home in his mouth to eat it in peace. Now on
his way home he had to cross a plank lying across a
running brook. As he crossed, he looked down and saw
his own shadow reflected in the water beneath. Thinking
it was another dog with another piece of meat, he made
up his mind to have that also. So he made a snap at the
shadow in the water, but as he opened his mouth the
piece of meat fell out, dropped into the water and was
never seen more.
Moral Lesson: Beware lest you lose the substance by grasping at the
shadow.
