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.
Taking on the mystery is yielding to grace, letting go of all explanations, analyses, ideologies, self-images, images of God, agendas, expectations. Taking on the mystery is undergoing the finitude of years, hallowing diminishments, and living into the solitude of our own integrity. Taking on the mystery is undergoing the pain of learning that there are no empires favored by the Holy One: not the Roman, or the British, or the Soviet, or the American. Taking on the mystery is undergoing the grief of understanding that there are no theologies favored by the Holy One: not communism or capitalism, not Islam, Judaism, or Christianity. Taking on the mystery is acknowledging that we cannot name the mystery, though we try; we cannot claim the mystery, though we do. The mystery names and claim us, inviting us to take it upon ourselves as if we were God's spies.
