"The Tao is teachable, yet understanding my words is not the same as following the Tao. The guidance is describable, yet knowing the description is not the same as following the guidance. Non-Being guides to the origin of Heaven and Earth. Being guides to the mother of all particular things. Thus, through the guidance of Non-Being, you can observe the beginning; through the guidance of Being, you can observe the returning. Non-Being and Being come out concurrently, but point to different directions; both together can be called the mysterious transforming power. They constantly transform into each other, and form the gateways for all wonderful things."
