Nan-in, a Japanese master was serving tea. He poured his visitor’s cup full, and then kept on pouring.
The visitor 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?”
One of my professors, Nick Bontis, phrased this thought very well in class. He said that because the world is always changing and that there is new information being generated every second, when do we humans ever take the time to let go of what we have already learned or acquired. The brain is not a bottomless container, it does have a limited capacity. Unlearning what was acquired to create space to learning ‘the unknown’ entices me.
