LIBRA (Sept. 23-Oct. 22): "The door to the invisible must be visible," wrote surrealist spiritual author Rene Daumal. This describes an opportunity on the verge of becoming available to you. It's still invisible simply because it has no precedents in your life; you can't imagine what it is. But recently a door to that unknown realm has become visible. Open it, even though you have no idea what's on the other side.
