The traditional view of a sage is an intellect that internally possesses virtue and outwardly acts as a ruler. However, Guo Xiang (also known as Kuo Hsiang) brought up another significance for a sage, namely "xiao-yao" (spiritual freedom or carefree and unrestrained wandering). Carefree and unrestrained sages are not different in identity, status, in governmental circles or not, just in "nature based." Creations differ greatly from each other in nature; nevertheless, all of them will free and get their spiritual freedom if they are able to be based on nature and fulfill their nature. "Nature Based Spiritual Freedom" is a kind of humble wisdom and a subjective state of life, and it absolutizes the specialty of individual thing. "Spontaneous Generation" (tzu-sheng) and "Self Transformation" (duhua) of creation do not rely on anything. Since propagation of creation is absolute, all links between identity and space-time are severed. It emphasizes the absoluteness of individual on the very moment. Approving integrality and self-contentness of oneself and everything, one is free and then everything is free. This is the most tactful doctrine of Taoism. Thereby, the sage theory of Guo Xiang's "Nature Based Spiritual Freedom" has its significance in the history of Chinese thoughts. Guo Xiang broke the limit of "chi" (temperament) of a sage; he considered that everybody is able to get spiritual freedom. He also evaporated "Ming Jiao" (Value Morals and Institutions, includes the proper behavior being matched to the proper role) which Confucian scholars (rujia) used to manage the world, and it transcendentalized traditional sages. Moreover, the school discipline had a deep and far influence from ontology of metaphysics to Buddhadhatu theory.
