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 the Great Spirit, and that this center is really everywhere, it is within each of us.
Gratitude is the most fruitful way of deepening your consciousness that you are not an "accident", but a divine choice. It is important to realize how often we have had chances to be grateful and not have used them. When someone is kind to us, when an event turns out well, when a problem is solved, a relationship restored, a wound healed, these are very concrete reasons to offer thanks.
What fascinates me so much is that every time we decide to be grateful, it will be easier to see new things to be grateful for. Gratitude begets gratitude, just as love begets love.
