"The Tao is like a well, used, but never used up. It is like the eternal void filled with infinite possibilities. It is hidden but always present. I don't know who gave birth to it. It is older than god."
The concept of infinity is hard for a human to conceptualize. All of human life is in constant state of transition and transformation until the full transformation out of human life and perhaps into something else. The unknown can be scary and also beautiful at the same time. Anticipation can be pleasureful and sometimes even more pleasing than whatever it is you await. The Tao is unending, ever-present and not always easy to perceive.
