Empty your Cup
====

A university professor went to visit a famous Zen master.
While the master quietly served tea, the professor talked
about Zen. The master poured the visitor's cup to the brim,
and then kept pouring. The professor watched the overflowing
cup until he could no longer restrain himself. "It's full!
No more will go in!" the professor blurted. "This is you,"
the master replied, "How can I show you Zen unless you first
empty your cup."
