“A visitor arrived inquiring about Zen. Master Nan-in silently poured him a cup of tea and continued pouring until the cup overflowed. “Why do you continue to pour after the cup is full?” asked the visitor. “To you show,” replied Nan-in, “that you are like this cup, so full of your own preconceptions that nothing can go in. I can’t tell you about Zen until you have emptied your cup.”
Consider what you know (or think you know) about dogs, and consider what you don‘t know. Have you emptied your cup so that you can see your dog purely for what he is rather than through the filter of human ideas?
