56 Those who know don't talk, and those who talk don't know.
Block the senses and close the mind,
blunt edges, loosen tangles, soften glare, mingle dust:
this is called dark-enigma union.
It can't be embraced and can't be ignored,
can't be enhanced and can't be harmed,
can't be treasured and can't be despised,
for it's the treasure of all beneath heaven.  
Chad Hansen 2009
56 Those who know to act do not speak. 
Those who speak, do not know to act. 
Shut up its exchanges, 
close its gates. 
Dull its sharpness, 
undo its divisions. 
Balance its brightness, 
treat its particles as identical. 
This is called the abstruse identity. 
Hence we cannot obtain and be close. 
Cannot obtain and be distant. 
Cannot obtain and benefit. 
Cannot obtain and harm. 
Cannot obtain and value. 
Cannot obtain and debase. 
Hence we deem the social world as valuable.      Moss Roberts 2001
56 Those who know it do not say it;
Those who sat it do not know it.
Those who know bar interaction,
Shut and seal the gates and doors;
They dull their keen edge and
Resolve their differences,
Reconcile the points of view
And blend with the lowly dust.
This we call sublime at-oneness.
Favour affects them not,
Nor disfavour,
Neither advantage
No injury,
Neither honour
Nor dishonour.
Thus those who know are honoured in the world.  
  Lok Sang Ho 2002
56
Those who know do not speak much.
Those who speak much do not know.
Block the passage of exchange with the outside world.
Close the doors;
Blunt the protruding points;
Absolve the disputes;
Tone down the dazzling light;
Receive outside stimuli with an equanimous mind.
This is called the mystical union.
With a non-possessive mind we get together;
With a non-possessive mind we separate.
With a non-possessive mind we experience what seems advantageous to us;
With a non-possessive mind we experience what seems disadvantageous;
With a non-possessive mind we experience high positions;
With a non-possessive mind we experience low positions.
This way we achieve the most valuable under heaven.      Gu Zhengku 1993
56 He who is wise will not speak;
He who speaks is not wise.
When one blocks the openings (of knowledge),
Shuts the door (of desires),
Dulls sharpness,
Stays away from entanglements,
Glows with veiled radiance,
Mingles with dust,
That is called subtle identification.
Hence you are in no way
To be friends with him,
To estrange him,
To benefit him,
To harm him,
To honor him,
To debase him.
That is why he is held in esteem in the world.     Lin Yutang 1948
56 Beyond Honor and Disgrace
He who knows does not speak; 
He who speaks does not know. 
   Fill up its apertures, 
   Close its doors, 
   Dull its edges, 
   Untie its tangles, 
   Soften its light, 
   Submerge its turmoil, 
   - This is the Mystic Unity. Then love and hatred cannot touch him. 
Profit and loss cannot reach him. 
Honor and disgrace cannot affect him. 
Therefore is he always the honored one of the world.  
Flowing Hands 1987
56 Those who are enlightened, sit in silence.
Those who think they know something, are forever talking.
In silence and peace one can become enlightened.
No one can teach someone else how to become enlightened,
for it stems from within the heart.
Be at one with Heaven and Earth and then you can become enlightened.
He who has become enlightened, is unconcerned with friends, enemies,
honour or disgrace, with wealth and titles.
For he has become at one with the Dao.
This is the highest state of man.
