Those Who Know Do Not Say

Those who know do not say
those who say do not know.
Close the senses,
shut the doors;
blunt the sharpness,
resolve the complications;
harmonize the light,
assimilate the world.
This is called mysterious sameness
It cannot be made familiar,
yet cannot be estranged;
it cannot be profited,
yet cannot be harmed;
it cannot be valued,
yet cannot be demeaned.
Therefore it is precious for the world.
