本文對《莊子》精、氣、神等概念，做系統性的詮釋和建構，尤其扣緊工夫和境界，以探討精氣神的層次性和發展性;筆者以存有的連續性之光譜一概急，來說明精氣神的差異性和統合性的關係。另外，亦企圖說明，精氣神不只是一套身體觀的觀念，它們同時也可和心性論、存有論、工夫論等語言相互溝通。就在其人遊乎神氣的形上境界中，精神化的身體、冥契式的心靈和根源性的存有，都取得根源的同一性，而精氣神就是同時呈現這些向度的共通性語言。

This article attempts to offer a systematic interpretation and construction of the concepts of ching 精, ch’i 氣, and shen 神 in Chuang Tze 莊子, especially with respect to practical methods 工夫 and mystical experience 境界, in order to explain the relationship between these three concepts in terms of their stages and the developmental process. In short, the author uses the concept of the “continuity of Being” to explain the differences between and the unity of these three concepts. The author also tries to show that these three terms are not just a set of concepts relating to the conception of the body, but at the same time also interact with the language of spirituality, ontology, and practical methods. While the Authentic Man 真人 plays with the cosmic vibration of inner metaphysical experience, the three dimensions of spiritual body, mystical consciousness and transcendental Tao gain their relationship of radical identity.
