A Zen Story

Though I am not very much into spirituality or philosophy, I love to read Zen stories as it is short and up to the point. Here is one such story

A Cup of Tea 

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 until he no longer could restrain himself. "It is overfull. No more will go in!" 

"Like this cup," Nan-in said, "you are full of your own opinions and speculations. How can I show you Zen unless you first empty your cup?"
