These one hundred and twelve methods are not really for developing the navel center; they are for uncovering it. That is why instantly sometimes one becomes a buddha, because there is no question of creating something. If you can look at yourself, if you can go deep down into yourself, all that you need is already there. It is already the case, so the only question is how to be thrown to that point where you are already a buddha. Meditation doesn't help you to be a buddha, it only helps you to become aware of your buddhahood.
