Some of us have cavernous vibrations inside us when we communicate with God. Others are more rational and less messy in our spiritual sense of reality, in our petitions and gratitude and expressions of pain or anger or desolation or praise. Prayer means that, in some unique way, we believe we're invited into a relationship with someone who hears us when we speak in silence.
Prayer can be motion and stillness and energy—all at the same time. It begins with stopping in our tracks, or with our backs against the wall, or when we are going under the waves, or when we are just so sick and tired of being psychically sick and tired that we surrender, or at least we finally stop running away and at long last walk or lurch or crawl toward something. Or maybe, miraculously, we just release our grip slightly.
Prayer is talking to something or anything with which we seek union, even if we are bitter or insane or broken. (In fact, these are probably the best possible conditions under which to pray.) Prayer is taking a chance that against all odds and past history, we are loved and chosen, and do not have to get it together before we show up. The opposite may be true: We may not be able to get it together until after we show up in such miserable shape.
But in any case, we are making contact with something unseen, way bigger than we could ever imagine in our wildest dreams, even if we are the most brilliant, open-minded scientists and physicists of our generation. It is something we might call divine intelligence or love energy (if there were no chance that anyone would ever find out about this). Prayer is us—humans merely being, as e. e. cummings put it—reaching out to something having to do with the eternal, with vitality, intelligence, kindness, even when we are at our most utterly doomed and skeptical.
My belief is that when you're telling the truth, you're close to God. If you say to God, "I am exhausted and depressed beyond words, and I don't like You at all right now, and I recoil from most people who believe in You," that might be the most honest thing you ever said. If you told me you had said to God, "It is all hopeless, and I don't have a clue if You exist, but I could use a hand," it would almost bring tears to my eyes, tears of pride in you, for the courage it takes to get real—really real. It would make me want to sit next to you at the dinner table.
