Epiphanies

Actually, I'm just making that up based on my own experience, but it sure sounds good, huh? I gather, though, that Zen is supposed to be the same way. For example, here's something Mu-mon said in the introduction to The Gateless Gate.

“Even such words are like raising waves in a windless sea or performing an operation upon a healthy body. If one clings to what others have said and tries to understand Zen by explanation, he is like a dunce who thinks he can beat the moon with a pole or scratch an itching foot from the outside of a shoe. It will be impossible after all.

What ideas have I understood in this way? The main one that comes to mind is the idea that words are not reality … and, of course, the one I'm working on right now, which is the idea that there's not enough time.
