Lifting the Tree

Once upon a time a man was walking in the woods when a tree fell on him. A neighbor passing by and seeing him lying under the tree said, "Lift it off." No one can deny that this was precisely what needed to be done. Unfortunately, the tree was bigger than the man and he couldn't lift it off.

Is this not the situation when people tell us not to be afraid, or not to get angry, or that we should love our fellow humans?
