"Wu-wei literally translates as “no trying” or “no doing,” but it’s not at all about dull inaction. In fact, it refers to the dynamic, effortless, and unselfconscious state of mind of a person who is optimally active and effective. People in wu-wei feel as if they are doing nothing, while at the same time they might be creating a brilliant work of art, smoothly negotiating a complex social situation, or even bringing the entire world into harmonious order. For a person in wu-wei, proper and effective conduct follows as automatically as the body gives in to the seductive rhythm of a song. This state of harmony is both complex and holistic, involving as it does the integration of the body, the emotions, and the mind. If we have to translate it, wu-wei is probably best rendered as something like “effortless action” or “spontaneous action.” Being in wu-wei is relaxing and enjoyable, but in a deeply rewarding way that distinguishes it from cruder or more mundane pleasures."
— Edward Slingerland, referring to the Chinese concept in his book Trying Not to Try
