The foundation of the exact measure

There is only one darkness,
an everything else is just an illegal construction,
which time returns back to darkness.

Only he who has accepted his essence,
the foundation of the exact measure,
is a constant:
“The darkness in me
and I in the darkness
in the world of illegal construction.”

Do you know how many suns
have already shone without measure
on the line of eternity of darkness?
Do not be among them,
lest you fade into the abyss of darkness.

It is enough to be what you are,
without yourself,
so that the bird inside you can build its nest.

But the time of ghosts is now upon us.
Is there anyone anywhere
in whom bird still chirps?
