Between Heaven and Earth, within the Six Harmonies, the Chi encompasses nine apertures, five viscera, and twelve joints, all connected to the cosmic atmosphere, representing the microcosm of the human body.
The microcosm of the human body corresponds to the macrocosm outside the body—if harmony is maintained between the two, it manifests as Unity of Heaven and Man.
Calculating celestial secrets through humanity, the most appropriate approach is to adjust the relationship between the microcosm inside the human body and the macrocosm outside.
If this relationship is well balanced, one can explore heavenly secrets without violating the Heavenly Dao and without fearing heavenly retribution.
This relationship was something Chen Dengming had mastered, yet the First Ancestor Longevity Dao Monarch had never accessed Unity of Heaven and Man.
