Often peace is taught as the fourth mark of existence. This isn't the peace that's the opposite of war. It's the well-being that comes when we can see the infinite pairs of opposites as complementary. If there is beauty, there must be ugliness. If there is right, there is wrong. Wisdom and ignorance cannot be separated. This is an old truth — one that men and women like ourselves have been discovering for a long time. Cultivating moment-to-moment curiosity, we just might find that day by day this kind of peace dawns on us, and we begin to understand what all the books have been talking about.
