I wanted to solicit thoughts on spontaneous qigong. My initial journey into tai chi and qigong involved the teachings of Sifu Wong Kiew Kit (WKK) some time ago. Per WKK, spontaneous qigong was the source of one's power. He taught that qi has a natural intelligence and it would seek out and fix your problems. I note that WKK taught primarily for health/martial arts. The spontaneous movements were more of an allowing --- I never felt strongly controlled by them although the more I relaxed into them, the stronger they got.    When I was on an intense Theravada retreat some time later, I began to manifest spontaneous movements. I asked the teacher about it, Bhante Rahula, who told me not to give in to the movements but just keep doing the practice (Vipassana). I intentionally stopped the movements. I felt a strange sort of pressure building, and then a fabulous internal display of fireworks occurred as things started to open inside, including my legs. This permanently changed how much pain I felt while sitting. These movements were very strong--- while I could intentionally prevent them, it felt like some thing else was controlling my body.    My anecdotal, uneducated theory is that the same energies can be externally expressed in spontaneous movements, or internally by opening channels and so on. If so, then it seems that spontaneous qigong might be good for martial arts (because it is about expressing) but not necessarily good for spiritual practices (which tend to use energy for more internal uses). I have not had a lot of teachings on this, so I thought I would see if anyone here had some thoughts and comments.
