Soul wounds and excercises to prevend qi loss

Hello Albor,
A direct answer to your question would be that this is done in the Fusion practices. Especially during the practice of the Belt Channel(s) in Fusion 2 and 3. The belt channels are circulated, spiraled, on multiple levels with the pearl, and this can help heal your energy body. Another aspect of this sort of healing done in Fusion is that you can call in any missing parts of your soul while taking energy into the Bagua and into the Cauldron. It’s really a profound practice, and I advise learning it from a teacher.
It should also be considered that this sort of healing is also done in the fundamentals, and also in Primordial Qigong (Wuji Gong), and Deep Healing Qigong. The Fundamentals alone do some of this sort of healing, and can also help you open the space for spontaneous healing of that sort. Read about Primordial Qigong at http://taichi-enlightenment.com/. In that practice energy is gathered from the directions, and much healing is done. Deep Healing Qigong does some work with the Belt Channel and other Extraordinary Vessels, and also with the vital organ Spirits, and more. It can also lead to great spontaneous healing.
For prevention, all qigong is good for that, including all that I listed aboove, beause your energy body becomes denser. The eight extraordinary vessels are the most important for strengthening your energy body (including the Governor and Conception vessels taught in the Fundamentals), as well as the inner smile so all flows in harmony.
I hope this helps.
