Enlightenment is not some good feeling or some particular state of mind. The state of mind that exists when you sit in the right posture is, itself, enlightenment. If you cannot be satisfied with the state of mind you have in zazen, it means your mind is still wandering about. Our body and mind should not be wobbling or wandering about. In this posture there is no need to talk about the right state of mind. You already have it. This is the conclusion of Buddhism.
