The gatekeeper of eternity

You are always in contact either with the known in front of you
or with the unknown inside of you,
and you only make pair with one of them
until the day it matures in your pair
and falls like an apple from a black-and-white tree
into the chosen world.

And the unknown will enter through your door
in front of your face as an eternal known,
for you were the gatekeeper of its eternity.

And the known will enter through your door
into the eternal world of the unknown,
for you were the gatekeeper of its eternity.
