I think joy and sweetness and affection are a spiritual path. We're here to know God, to love and serve God, and to be blown away by the beauty and miracle of nature. You just have to get rid of so much baggage to be light enough to dance, to sing, to play. You don't have time to carry grudges; you don't have time to cling to the need to be right.
Knowing yourself is not so much about introspection as interaction. To know yourself is to realize that you are more than the little self that has been given to you by your history—the pattern that others made—that your true self is, in truth, much larger and includes other people, other cultures, other species even. That life is less about BEING and more about INTERBEING. We come to know ourselves, then, through coming to know each other. And the deeper that knowledge, the richer and more creative the world we build together.
