Tao Te Ching · Ch. 26

重為輕根,靜為躁君。是以聖人終日行不離輜重。雖有榮觀,燕處超然。奈何萬乘之主,而以身輕天下?輕則失根,躁則失君。

Zhòng wéi qīng gēn, jìng wéi zào jūn. Shì yǐ shèng rén zhōng rì xíng bù lí zī zhòng. Suī yǒu róng guān, yàn chǔ chāo rán. Nài hé wàn shèng zhī zhǔ, ér yǐ shēn qīng tiān xià? Qīng zé shī gēn, zào zé shī jūn.

Heaviness is the root of lightness; stillness is the master of restlessness. Therefore the sage travels all day without leaving his supply-wagon. Though there may be splendid views, he dwells at ease, unmoved. How then can a lord of ten thousand chariots govern the realm with his own person lightly? To be light is to lose one's root; to be restless is to lose one's mastery.
