Meditation is something I would like to try. Recently I went to a zen dojo to try. They sit on this zafu cushion in a position I am not flexible enough to do. Even trying half of the position hurt incredibly. But the worst part was after the meditation, when one of the students asked a question to the master. The master then talked for a very long time, digressing on different parts of his life, mocking his students, and boasting about his superiority, which he tried to demonstrate by misquoting all sorts of people. I wondered if listening to the master was also pain the students are supposed to overcome. I won't go back there. I'll have to try meditation somewhere else.
You can stretch and acclimate your knees to the sitting position, unless you have a major existing medical condition or something. It comes with time.
The next thing that will come up is that zazen can be incredibly boring.
(It is.)
But it helps.
Also, sometimes people considered authority figures act like dicks. Sometimes people cut their authority figures slack because they're "enlightened", or whatever.
