Well, I think it's a twin, the darkness and light. The object is still the same, unique. Like you, like me. Light and darkness are always in motion, in changes, even Earth hasn't her own light, still turning around herself and Sun. So we have life, sounds, smiles, tears in motion... like productivity, thoughts, experiences... in motion. Communicating with us, our space, our time like a little kid. Some minds have knowledge of this nature. Others make a living from that knowledge, others still worry about adding ignorance to their everyday problems and others live with this phenomenon. It's about our other half, of time, the other half of our image, or destiny. It's kind of another person matching our state of being, time, space. All we need to do is to welcome our other half and see ourselves with love about solving the question of the unidentified state of us creating the best connection with ourselves about that movement, motion, emotion. Live better, feel better.
