This involves meditative and moral practices. Important in this respect is the Taoist concept of De (; virtue). In Confucianism and religious forms of Taoism, these are often explicitly moral/ethical arguments about proper behavior, while Buddhism and more philosophical forms of Taoism usually refer to the natural and mercurial outcomes of action (comparable to karma). The Tao is intrinsically related to the concepts yin and yang (pinyin: yīnyáng), where every action creates counter-actions as unavoidable movements within manifestations of the Tao, and proper practice variously involves accepting, conforming to, or working with these natural developments. De De ( "power; virtue; integrity") is the term generally used to refer to proper adherence to the Tao; De is the active living or cultivation of the way. Particular things (things with names) that manifest from the Tao have their own inner nature that they follow in accordance with the Tao, and the following of this inner nature is De. Wuwei (Pinyin: wúwéi) or "naturalness" is contingent on understanding and conforming to this inner nature, which is interpreted variously from a personal, individual nature to a more generalized notion of human nature within the greater Universe. Historically, the concept of De differed significantly between Taoists and Confucianists. Confucianism was largely a moral system emphasizing the values of humaneness, righteousness, and filial duty, and so conceived De in terms of obedience to rigorously defined and codified social rules. Taoists took a broader, more naturalistic/metaphysical view on the relationship between humankind and the Universe and considered social rules to be at best a derivative reflection of the natural and spontaneous interactions between people and at worst calcified structure that inhibited naturalness and created conflict. This led to some philosophical and political conflicts between Taoists and Confucians. Several sections of the works attributed to Chuang Tzu are dedicated to critiques of the failures of Confucianism. Religious, philosophical, and cultural interpretations Taoist interpretations [Tao] means a road, path, way; and hence, the way in which one does something; method, doctrine, principle. The Way of Heaven, for example, is ruthless; when autumn comes 'no leaf is spared because of its beauty, no flower because of its fragrance'. The Way of Man means, among other things, procreation; and eunuchs are said to be 'far from the Way of Man'. Chu Tao is 'the way to be a monarch', i.e. the art of ruling. Each school of philosophy has its tao,
