A rich hypochondriac sits in front of a famous zen monk to discuss his problems, when a bee comes into the room and starts hitting itself against the window pane repeatedly. The zen master seems absorbed in the bee and the hypochondriac becomes unsure if the master is still listening to him.
"Your highness. You seem to have a great interest in the bee."
"Oh I am sorry. I just pity this bee very much. My temple is famous for being old and having many draft holes. But this bee thinks it must hit this one place and cannot think of anything else. It will soon die if it keeps doing that. But it is not only the bee I should be pitying."
