Could you describe, blow by blow, what it's like when you meditate?

I’m looking for a kind of diary—the kinds of things you think (or don’t think) about. When thoughts pop up; what they are; what you feel physically; what you feel emotionally. This should be both when you start, and then later on, when you know more about what you’re doing.

I don’t care about any post-facto evaluations of yourself, but if you think that kind of thing during the meditation, I am interested. Maybe, at the end, you could say whether you thought it was worth it or not, and why you have that opinion, if it isn’t obvious from your description of what happened.

I read an article about it this morning, and since the article was about someone I know personally, it peaked my interest. It generally seems so mysterious. People either are reluctant to describe it, or say they can’t describe it. I guess this is my request that you try.
