"Buddhism does not advocate faith in the sense of believing something because it is written in a book, attributed to a prophet, or taught to you by some authority figure. The meaning of faith here is closer to confidence. It is knowing that something is true because you have seen it work, because you have observed that very thing within yourself. In the same way, morality is not a ritualistic obedience to a code of behavior imposed by an external authority. It is rather a healthy habit pattern that you have consciously and voluntarily chosen to impose upon yourself because you recognize its superiority to your present behavior."
