Those who are wise do not speak about wisdom,
And those who speak about wisdom are not wise.
Shut your mouth,
Close your eyes,
Blunt your edges,
Untie your knots,
Unwind your intellect,
And identify yourself with the dust.
This is how you achieve unity with the world.
Once unity with the world is achieved,
You will no longer be able to be attached, nor aloof,
Nor benefited, nor harmed,
Nor ennobled, nor disgraced.
This is the highest state of human development.
