The Great Nature is Waning
At the last part of the 7th chapter (The Normal Course for Rulers and Kings) of the book [Zhuang Zi] says:
The ruler of the Southern ocean 'Cho' and the ruler of the Northern ocean 'Hu' often meet each other at the center land which is ruled by 'When-tun' (Chaos). When-tun treated them very well. Cho and Hu wanted to repay When-tun's kindness and said to each other : "Everyone has 7 orifices for them to see, to listen, to eat, and to breath, but only this one does not have any, let's try to make them for this one." Then they dug one orifice each day, 7 days later, When-tun died.
莊子希望人類重歸自然,這個自然是先於人類文明. 這個自然就是那個好心待客卻沒得到好報,被南海與北海鑿成七竅而死去的渾沌. 渾沌意味著大樸,七竅意味樸散而生的智巧... 七竅一成,大樸彫散,渾沌必死 ... 語出葛翰聰＜中國琴學源流論疏＞
