There are other types of vital energy also available: Orgone and æther. In my experience each one is different. To understand the role of jing, chi and shen we have the popular analogy of the candle, the jing is the candle, the chi is the fire and the shen is the light that that fire emits. Jing will always strengthen your organs, hormones and cells, chi is the source of energy that makes everything above work and store energy. Shen strengthens your consciousness and your spiritual and psychic abilities.
The difference with all jing and chi is that they are directed to different parts and some are more refined or more intelligent than others, but there is a problem that I have noticed and is that these energies, if you do not circulate them, are of little use to you and tend to stagnate. in your lower dantian. It is important to do physical activity to circulate and take better advantage of these energies, practicing qigong is ideal.
By the way, I think it is not necessary to use the shen audios too much because if you have enough jing and chi, the shen cultivates itself as long as you meditate or do spiritual practices. A long time ago I stopped using shen because I also noticed that it comsume my jing and chi to form, apparently my reserves of these energies are not yet large enough to sustain an excess of shen. Or need more loops fot saturation.
and jindan, I haven’t used it much but I haven’t noticed any increase in energy, or any notable effect beyond being a bit relaxing.
Moles are due to melanocytes changes, might be related to fast overexposure to sun, or anything that quickly changes their composition, AFAIK stimulation of melanocytes is something that leads with continuous exposure to increase of melanoma risk.
