“Once upon a time an academic scientist went to visit a Zen Master, famous for being very wise. After greeting the scholar, the master offered him tea. As they sat together, the monk began to pour the tea into the scholar's cup. He poured until the tea overflowed onto the saucer, then the table and finally onto the floor.

When the scholar could not stand it any more, he blurted out: "Stop, stop, can't you see the cup is full?" To which the Zen Master replied: "Yes, I can, and until your mind is empty, you will not hear what I have to say.”
