What is the theme in Tao Te Ching by Stephen Mitchell?

"Not-doing" is the mysterious way in which the Tao makes things fall into place. The Tao "does nothing but through it all things are done." The Tao is beyond value and no one can achieve it. Above all, trying to control the future is like an amateur using a master carpenter's tools and, inevitably, getting cut. Although people build wheels, craft pots, and construct houses, it is the space within that functions because people work with being, but use non-being.
