第一章：道可道，非常道；名可名，非常名。无名，天地之始；有名，万物之母。故常无欲，以观其妙；常有欲，以观其徼。此两者，同出而异名，同谓之玄。玄之又玄，众妙之门。
The Way that can be told of is not an Unvarying Way; The names that can be named are not unvarying names. It was from the Nameless that Heaven and Earth sprang; The named is but the mother that rears the ten thousand creatures, each after its kind. Truly, 'Only he that rids himself forever of desire can see the Secret Essences' ; He that has never rid himself of desire can see only the Outcomes. These two things issued from the same mould, but nevertheless are different in name. This ' same mould' we can but call the Mystery, Or rather the 'Darker than any Mystery', The Doorway whence issued all Secret Essences.
