The real existence of an enemy upon whom one can foist off everything evil is an enormous relief to one's conscience. You can then at least say, without hesitation, who the devil is; you are quite certain that the cause of your misfortune is outside, and not in your own attitude.
The nonviolent approach does not immediately change the heart of the oppressor. It first does something to the hearts and souls of those committed to it. It gives them new self-respect; it calls up resources of strength and courage that they did not know they had. Finally it reaches the opponent and so stirs his conscience that reconciliation becomes a reality.
