"There is something, chaotic yet complete, which existed before Heaven and Earth. Oh, how still it is, and formless, standing alone without changing, reaching everywhere without suffering harm It must be regarded as the Mother of the Universe. Its name I know not. To designate it, I call it Tao. Endeavoring to describe it, I call it Great. Being great, it passes on; passing on, it becomes remote; having become remote, it returns."
