The Tao is a cosmic force that can't be named or described, which is the natural harmony between all living things, and the way they all move together. Taoists thought that if someone "forgot themselves", and let go of intentions, they would be able to "move effortlessly" (wu wei, or "non-action"), and be in harmony with the Tao, like the animals, plants, and everything else. This harmony is the ultimate goal of Taoism.
