G.K. Chesterton spoke of the “mystical minimum,” which he defined as gratitude. When we stand in the immense abundance of the True Self, there is no time or space for being hurt. We are always secure, at rest, and foundationally grateful. The grateful response for what is given—seeing the cup half full— requires seeing with a completely different set of eyes than the eyes that always see the cup as half empty. I don’t think it’s an oversimplification to say that people basically live either in an overall attitude of gratitude or an overall attitude of resentment. The mystical minimum is gratitude: Everything that is given—that we are breathing today—is pure gift. None of us have earned it. None of us have a right to it. All we can do is kneel and kiss the ground—somewhere, anywhere, everywhere.
