1 The inner refining of jing, qi, and shen: The first stage is to refine jing into qi. That is to keep the acquired jing from leaking and reversing its direction, so it would go upwards [to temper jing into qi.]
2 Humans consume the five grains, and a variety of foods and beverages, but in the end, these things change to yin jing. The yin jing of the body is not true jing. However, true fire causes transformation to Qi, and in the process, our yin jing is smelted and made pure. Our acquired jing, qi, and shen are thus refined. Their movement is reversed, and finally, they return to their origin, becoming true jing, true qi, and true shen. These are the primal jing, qi, and shen, which are innate to us.
3 Jing, qi, and shen cannot be seen in the body, and they are hard to define. Compared to the physical side of the universe, jing can be likened to the heat of the living body; qi can be likened to force, and shen can be likened to light.
4 The composition of bodily jing is neither light nor dark, and is partly yin and partly yang. Innate Qi is neither the qi that makes up the atmosphere, nor is it the qi we breathe. “Qi is the ultra-yang energy flow that is produced when high-level etropic substance from harmonons combines with bodies of static etropicity.” The upper part of the [Chinese] character is 旡 [pronounced wu], meaning nonbeing, and the four dots below symbolize fire. We can characterize such Qi as the innate Qi.
5 There are locations in the body where the three treasures of jing, qi, and shen are matched with bodily functions. Jing is in the area of the kidneys, qi is in the area of the chest cavity, and shen is in the head.

 Five grains refer to rice, beans, wheat, soybeans and yellow millet.
 "True fire" is acquired qi which has been transformed into spirit-yang qi. It is no longer acquired, but has become innate. See Chapter 3 "Tempering the mind to transform self-nature" of the Mystic Epochal Treasures of the Cosmos.
 From this we can see that qi is produced from the interaction of a harmonon with material particles. According to the Church's doctrine, constituents of material objects are particles called "etropons." Etropons have either yin or yang polarity, and the attractive force between them is called etropicity. Etropon bodies may attract and temporarily hold spirit-entities called harmonons. Though harmonons are spirit-energy, they contain some etropic substance. See A New Realm, Part I.
