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-Taka (the Great Spirit), and that 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,
 and 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.
