The first peace which is the most important is that which comes within the souls of people when they realize their relationship, their oneness, with the universe and all its powers, and when they realize that at the center of the universe dwells Wakan-Tanka (The Great Spirit), and this center is really everywhere, it is within each of us. This is the real peace, and the others are but reflections of this.
The second peace is that which is made between two individuals. The third is that which is made between two nations.
But above all, you should understand that there can never be peace between nations until there is known that true peace, which as I have often said, is within the souls of men. Black Elk
