"Those who know do not speak; Those who speak do not know. Black the passages, Shut the doors, Let all sharpness be blunted, All tangles untied, All glare tempered. All dust smoothed. This is called the mysterious leveling. He who has achieved it cannot either be drawn into friendship or repelled, Cannot be benefited, cannot be harmed, Cannot either be raised or humbled, And for that very reason is highest of all creatures under heaven."

- ~Lao Tzu, The Way and Its Power.
