The tree which needs two arms to span its girth sprang from the tiniest shoot. Yon tower, nine stories high, rose from a little mound of earth. A journey of a thousand miles begins with a single step.
As it acts in the world, the Tao is like the bending of a bow. The top is bent downward; the bottom is bent up. It adjusts excess and deficiency so that there is perfect balance.
There are three layers to the universe. In the lower, Tai Ching, and the middle, Shan Ching, the hindrance of a physical bodily existence is required. Those who fail to live consistently in accord with the Tao reside here. In the upper, Yu Ching, there is only Tao: the bondage of form is broken, and the only thing existing is the exquisite energy dance of the immortal divine beings.
