Qigong is the Ancient Chinese art of energy working. It’s detailed, technical and very powerful. Emphasis is on reading and working with your own qi (ki, prana, lifeforce), understanding your energy (qi) body and how to balance it’s state for optimal health, as well as develop more energy to become stronger and healthier.
This is the same qi used by the external martial arts in Tai Chi Chuan, Kung Fu, Aikido, and various Jutsu styles that use the meridians and points. It’s the same qi balanced via acupuncture techniques. It’s also the same energy used through symbols in Reiki.
In qigong, developing astral skills is a “side effect” that students are encouraged to ignore as distractions and are not really taught about. masters that “show off” can have their energy blocked by ascended masters (experts) who do not want this used for baneful or selfish reasons, or they may just withdraw their support and mentoring.
