Tao called Tao
is not the eternal Tao.
Names that can be named
are not the eternal name.
Nameless: heaven & Earth’s origin.
Naming: mother of ten-thousand things.
Ever desireless, one sees mystery.
Ever desiring, one sees manifestations.
These two spring from the same source,
but differ in name;
this appears as darkness.
Darkness within darkness.
The gateway to all mystery.
