Tao Te Ching · Ch. 45

大成若缺,其用不弊。大盈若沖,其用不窮。大直若屈,大巧若拙,大辯若訥。躁勝寒,靜勝熱。清靜為天下正。

Dà chéng ruò quē, qí yòng bù bì. Dà yíng ruò chōng, qí yòng bù qióng. Dà zhí ruò qū, dà qiǎo ruò zhuō, dà biàn ruò nè. Zào shèng hán, jìng shèng rè. Qīng jìng wéi tiān xià zhèng.

The greatest perfection seems incomplete, yet its usefulness is never exhausted. The greatest fullness seems empty, yet its usefulness is never spent. The greatest straightness seems bent; the greatest skill seems clumsy; the greatest eloquence seems to stammer. Activity overcomes cold; stillness overcomes heat. Pure stillness is the right order of the world.
