 While this may not be able to detract entirely from the charge of fatalism, Guo Xiang does aim to introduce a dynamic view of nature and destiny. It also opens up a deeper dimension to the notion of sagehood. The Daoist world is never static; it changes and renews itself constantly. The mountain or ocean may appear unchanging, but it is perpetually in flux. This is mirrored in human existence, where individuals grow with the passage of time (commentary to Zhuangzi 6). Although constituted by qi and regulated by principles, individuals and societies need not be viewed as fixed assets without possibility of change and development. Indeed, while the order of nature must be respected, the person of Dao recognizes the inevitability of change. The sage nourishes his nature and adapts constantly to changes in the social and natural environment. This, as Guo Xiang sees it, brings out the real meaning of Daoist nonaction (wuwei).
