The Heart of Understanding gives us solid ground for making peace with ourselves, for transcending the fear of birth and death, the duality of this and that. In the light of emptiness, everything is everything else, we inter-are, everyone is responsible for everything that happens in life. When you produce peace and happiness in yourself, you begin to realize peace for the whole world. With the smile that you produce in yourself, with the conscious breathing you establish within yourself, you begin to work for peace in the world. To smile is not to smile only for yourself; the world will change because of your smile. When you sit in the silence, if you enjoy even one moment of sitting, if you establish serenity and happiness inside yourself, you provide the world with a solid base of peace. If you do not give yourself peace, how can you share it with others? If you do not begin your peace work with yourself, where will you go to begin it? To sit, to smile, to look at things and really see them, these are the basis of peace work, love and unity.
