The way that can be spoken of
Is not the constant way;
The name that can be named
Is not the constant name.
The nameless was the beginning of heaven and earth;
The named was the mother of the myriad creatures.
Hence always rid yourself of desires in order to observe its secrets;
But always allow yourself to have desires in order to observe its manifestations.
These two are the same
But diverge in name as they issue forth.
Being the same they are called mysteries,
Mystery upon mystery -
The gateway of the manifold secrets.
