Nan-in, a Japanese master during the Meiji era (1868-1912), received a university professor who came to inquire about Zen.
Nan-in served tea. He poured his visitor's cup full, and then kept on pouring.
The professor watched the overflow...
It was a little late in the Sunday afternnon, a jobless old man walked into the Museum of History of Natural Sciences in Washington DC.
During walking there he happened found himself in the room where the famous diamonds such as the Hope... and others called gem-stones displayed neatly and meticulously in the glass boxes. When he was taking a look around he saw there were a lot of people glued their eyes to the stones, especially the pretty women followed by the handsome men.
He then stood against the wall of the room and said to himself: "All of them look alike and they all are stones. Right?"
People turned around and stared at him. He smiled. Some smiled, some laughed. Some kept looking at the stones, and some walked out of the room quietly.
The jobless old man also walked out of the room and left the museum.
