Story Summary
Discover the Zen story of Nan-in Serves Tea, where a master uses an overflowing teacup to teach a proud professor the importance of an open and empty mind.
During the Meiji era, a university professor went to visit the Zen master Nan-in to inquire about Zen. As Nan-in served tea, he poured his visitor's cup full, and then kept on pouring. The professor watched the tea spill over the rim and spread across the table until he could no longer restrain himself. 'It is overfull. No more will go in!' he exclaimed. Nan-in stopped pouring and looked at the man. '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?'
