I don't know if this quite qualifies, but I've always particularly liked this one:

Talking about Zen all the time is like looking for fish tracks in a dry river bed.

Can't remember who said that. Some ancient Chinese dude. Hui Neng maybe?
grumio Reviewed by grumio on . Alan Watts - You're Going to Believe This Passasge on the Divided Mind: As the Philospher tries to stand outside himself and his thoughts, so, as we have seen, the oridinary man tries to stand outside himself and his emotions and sensations, his feelings and desires. The result is a fantastic confusion and misdirection of conduct which discovery of the mind's unity must bring to an end. By Alan Watts anyone got any other great (philosphical) quotes? Rating: 5
