A nascent Dao Domain, gradually nurtured from the combination of Chen Dengming's Essence, Qi, Spirit, and Daoist Charm, and developed through his understanding of the Dao of Heaven's Life and Death.
Life and death divide yin and yang, much like the Tai Chi's dual aspects, cycling endlessly, akin to a cosmic egg, forming the center of the Dao Domain.
From this cosmic egg of life and death, yin and yang, Heaven first gestated and formed an embryonic human shape.
In Chen Dengming's understanding of Unity of Heaven and Man, the human body's neck and above resemble Heaven, while below the neck resembles Earth.
Humans have three hundred and sixty-six small joints, thus a year has three hundred and sixty-six days.
Humans have twelve major joints, hence there are twelve months in a year.
The five viscera of humans correspond to the five elements, and the limbs correspond to the four seasons.
His theory enriched the relationship between Heaven and Man.
