Tao Te Ching - Lao Tzu - chapter 45
Great accomplishment seems imperfect,
Yet it does not outlive its usefulness.
Great fullness seems empty,
Yet it cannot be exhausted.
Great straightness seems twisted.
Great intelligence seems stupid.
Great elequence seems awkward.
Movement overcomes cold.
Stillness overcomes heat.
Stillness and tranquility set things in order in the universe.
(as translated by Gia-fu Feng and Jane English)
