"As a Zen poem says, 'when two Zen masters meet each other on the street, they need no introduction. When thieves meet, they recognize one another instantly.' So a person who is a real cool Zen understands that, does not go around 'Oh, I understand Zen, I have satori, I have this attainment, I have that attainment, I have the other attainment,' because if he said that, he wouldn't understand the first thing about it." ~Alan Watts
