The word Tao means path or way, although the original meaning in Chinese philosophy and religion is more abstract. Behind all material things and all the change in the world lies one fundamental, universal principle which is the Way or Tao.
This principle governs everything, all change and all life. Behind the multiplicity and contradictions of the world lies a unity: the Tao. The Power of the Way is Te. The purpose of human life is to live life according to the Tao.
"Beyond the gate of experience flows the Way,
Which is ever greater and more subtle than the world."
From the Tao Te Ching

The world that can be constructed is not real."

"The Tao that can be told of is not the eternal Tao;
The name that can be named is not the eternal name.
The Nameless is the origin of Heaven and Earth;
The Named is the mother of all things.
Therefore, let there always be non-being, so we may see their subtlety,
And let there always be being, so we may see their outcome.
The two are the same,
But after they are produced, they have different names.
They both may be called deep and profound.
Deeper and more profound,
The door of all subtleties!"
