Actually, it says almost everything about meditation.

I definitely recommend that you (or anyone else interested) give meditation a shot-- but I'd suggest that you find a teacher. Otherwise, it's a bit like trying to learn to swim from a book.

There are a lot of meditation centers around, and most of them don't charge money or require adherence to any doctrine whatsoever. In my experience, they are happy to have you there, and happy to show you how it's done.

That being said: as books go, Bhante G.'s is one of the best.
