Zheng Xuan's“Six Heavens Theory”is grounded in the Huntian(Celestial Sphere) cosmology, where formless primordial qi(元气)envelops the tangible earth and interacts with it to generate life. Both the earth and all things are differentiated manifestations of the Supreme Heaven(昊天), unified within the holistic Dao of Heaven. In this framework, the“Five Celestial Emperors”(五天帝)(Heaven manifested on earth)emerge as localized expressions of the Supreme Heaven(Heaven in the cosmos),products of the dynamic interplay between heaven and earth. They manifest“temporally”within specific spatiotemporal domains and“contextually”through diverse human perspectives. Kong Yingda's classical interpretation—"Heaven as substance(体),Emperor as virtue(德)”— elucidates the relationship between the singular Heaven and the Five Emperors as one of substance and function. The Five Emperors are distinguished by their particularity and functional efficacy, contrasting with the Supreme Heaven's formless, quiescent nature. While the Supreme Heaven does not directly generate or govern, the Five Emperors— imbued with personhood,will, and sovereignty— act as direct creators and administrators of all beings. Zheng Xuan's system further distinguishes four dimensions of Heaven:ontological Heaven(本体之天),primordial-qi Heaven(元气之天), celestial-phenomena Heaven(星象之天),and virtuous-function Heaven(德用之天). These dimensions, though distinct,form an integrated whole, reflecting the Dao of Heaven through the interplay of substancefunction(体用)and manifestation-concealment(显隐). The metaphysical-physical dimensions of Heaven can be divided into ontological Heaven and primordial-qi Heaven,which share a substance-function relationship. Between ontological Heaven(Taiyi) and virtuous-function Heaven(the Five Emperors), there exists both a substance-function and a manifestation-concealment relationship. Similarly, primordial-qi Heaven and celestial-phenomena Heaven(symbolized by the North Star) also exhibit a substance-function relationship,while ontological Heaven(Taiyi)and celestial-phenomena Heaven(North Star) are linked through manifestation-concealment. Additionally, primordial-qi Heaven and virtuous-function Heaven(the qi of the Five Phases)share a substancefunction relationship. Further distinctions reveal that within celestial-phenomena Heaven, the North Star(symbolizing the Supreme Heaven)and the Five Emperor Star Thrones(symbolizing the Five Emperors) are bound by a hierarchical relationship(统属). Likewise, within virtuous-function Heaven, the Five Emperors and the Five Phases'qi(五行之气)they govern also exhibit a hierarchical relationship. Moreover,the Five Emperors and their symbolic Five Emperor Star Thrones share a manifestation-concealment dynamic. Together, these six symbols —— Taiyi(太一), primordial qi,North Star, Five Emperor Star Thrones, Five Emperors, and Five Phases’qi—interact through ten relational pairs, forming the substance-function and manifestation-concealment structure central to Zheng Xuan's Six Heavens Theory.
