The mind of a Zen Master is perfectly straightforward. He has neither front nor back and is without deceit or delusion. Every hour of the day, what he hears and sees are ordinary sights and sounds, but nothing is distorted. He is perfectly unat- tached to things, and thus doesn't need to shut his eyes and ears. Because he has eliminated delusion, perverted views, and bad thinking habits, he is as clear and tranquil as an autumn stream. Someone who is like this is called a Master of Zen, a man who has freed himself from all attachments. (Kuei-Shan 771-853)
