1. The qi of human
1.1. Congenital qi
Congenital qi is derived from the essence of ovum and spermatozoon. Reaction of the two congenital qi’s and its subsequent gathering and condensation results in the formation of the zygote and eventually the foetus.
1.2. Xian tian qi (before heaven qi)
The foetus takes nourishment from the mother through the umbilical cord. The essence (jing) from the mother to the foetus through the umbilical cord transforms into qi which reacts with the congenital qi of the foetus to form “xian tian qi” or foetus qi.
1.3. Yuan qi
After birth, the xian tian qi is stored in the kidneys as “yuan jing” or original essence. Throughout the life of the human, yuan jing is progressively converted into qi (more specifically, "yuan qi" or original qi) and released into the lower “dan tian” (located slightly below the navel).
1.4. Chen qi or Hou tian qi (after heaven qi)
The baby starts to take in air through his nose and food through his mouth and subsequent life processes which takes place in the relevant organs results in the formation of “chen qi” or “hou tian qi” (or post natal qi). This hou tian qi is stored in the middle dan tian which is located at the solar plexus.
1.5. Dispersal of yuan qi and chen qi
Yuan qi from the lower dan tian and chen qi from the middle dan tian are released into the “ren mai” and “du mai” (the conception and governing vessel) where they are blended to become one and then distributed throughout the entire body to sustain the life of the human.
1.6. Wei qi or guardian qi
Wei qi is a layer of qi that covers the skin and even extends beyond the body. It forms a shield protecting the body against outside influences such as cold and pathogens.
The entire qi system of the human body forms the human "qi body". An andvanced qigong practitioner would be become aware of this qi body as a feeling of the entire body "moving/feeling like water."
2. The human body or form
The human body or form is just simply the physical body of the human, it’s shape, and appearance.
3. The messages encoded in the human
Messages encoded into the human genes determine the physical as well as mental and even health characteristics of the human.
From the Hun Yuan Qi principle of zhineng qigong, the qi of human (human qi body), the body and the messages encoded in the genes of the human form the human hun yuan qi.
