The Dao that can be stated, is not the eternal Dao;
The name that can be named, is not the eternal name.
The unnamed is the origin of heaven and earth;
The named is the mother of the myriad things.
Therefore,
Constantly having no desire in order to view its commencement;
Constantly having desire in order to view its termination.
These two have the same origin, but they differ in name;
Both are called Mystery.
Mystery after Mystery, is the gate to all wonders.
