In chapter sixty-seven of the Daodejing, Laozi names three treasures he holds: compassion, from which comes courage; frugality, from which comes generosity; and not presuming to be ahead of the world, from which comes leadership. In later Daoism the phrase also names the vital essence, energy and spirit.
