“During the Meiji era, the Japanese Zen master, Nan-in had a visitor from a respected university – a professor who wanted to learn about Zen. Nan-in served the professor a pot of tea, but when the cupwas full, he continued pouring until the cup was overflowing. The startled professor watched in amazement until he could no longer restrain himself from intervening, “The cup is full and no more will go in. You’re making a mess!” “Like this cup,” Nan-insaid, “You are full of your own opinions, artificial concepts and negative speculations. How can I show you Zen unless you first empty your cup?” Like the learned professor who wanted to understand spirituality, you too must empty your cup and have an open mind and heart.”
