There was a story about a man comes to the Zen master,
and he’s a university professor
who has studied all the Zen scriptures
and all the other Buddhist scriptures,
and so he comes to the famous master and the master says,
“Sit down, please,” and the professor says,
“Well, I’ve studied it all,
but I want to hear from you also what really Zen is.
Can you explain the essence to me?”
And the master was making tea, so the master was,
there was the cup, the professor’s cup,
and the master took a teapot and started pouring tea
into his cup, and he didn’t stop pouring.
And then the tea overflowed,
and the professor was looking saying, “Stop, stop.
Can’t you see the cup is overflowing?”
