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.
