Laozi — "The sage governs by emptying senses and filling bellies."

"The sage is like water, which flows to the lowest places and yet is the strongest."

"The best of men is like water. Water benefits all things and does not compete with them. It dwells in lowly places that all disdain. This is why it is so near to the Tao."

"Knowing others is intelligence; knowing yourself is true wisdom. Mastering others is strength; mastering yourself is true power."

"Careful, like crossing a river in the winter. Wary, as if surrounded by strangers."

"Keep your mouth shut, guard your senses, and you will be free from trouble. Open your mouth, always be busy, and you will be beyond hope."
