top ten reasons why zen is like sex:
10. it's ok to do it by yourself, but it's even better with others.
9. you can do it anywhere under any circumstances, but beautiful, natural surroundings are ideal.
8. some people insist that there's only one right way to do it. these people should be avoided.
7. the people who talk about it the most tend to know the least.
6. flexibility is a plus.
5. falling asleep is considered very bad form.
4. some people like to dress up and use props - other people think that's ridiculous. don't knock it if you haven't tried it.
3. different people prefer different positions.
2. in the old days there was both a gradual approach and a sudden approach, but these days everyone wants to take the sudden approach.
1. you can read about it all you want, but unless you are doing it you have no idea.
