The tao that can be told is not the eternal Tao The name that can be named is not the eternal Name. The unnamable is the eternally real. Naming is the origin of all particular things. Free from desire, you realize the mystery. Caught in desire, you see only the manifestations. Yet mystery and manifestations arise from the same source. This source is called darkness. Darkness within darkness. The gateway to all understanding.
LaoziHeaven's Way is like stretching a bow. The high is lowered and the low is raised. Excess is reduced and deficiency is replenished. Heaven's Way reduces excess and replenishes deficiency. People's Way is not so. They reduce the deficient and supply the excessive.
Laozi
