The route you can traverse

isn't a static route.

The name you can dereference

isn't a universal name.

Namelessness is the root of everything.

Names are the mother of everything.

Therefore,

the unchanging, seen from outside the box,

reveals its inner nature;

the unchanging, seen from inside the box,

reveals its outer form.

These two are alike in origin,

but different in name.

Their unity is called "the mystery".

Mystery of all mysteries,

the gate to all wonders.

[As Le Guin says, a perfect translation

of this verse is perfectly impossible.]
