Why the Tao resists simple definition
One of the first lessons of Daoist thought is that the Tao cannot be captured neatly in a formula. The moment you reduce it to a concept you can fully control, you have already stepped away from what it points to.
This is why Daoist texts often speak indirectly, through paradox, image, and contrast. The goal is not to confuse for its own sake, but to protect the living quality of the idea.
