So those are probably the worse two examples you can find...not saying they are not good examples. I'm saying they are extreme examples of failure...the first video, I do not know anyone who claims those skills. No martial artist, or practitioner of the internal arts. I know guys like that are out there, but I've yet to meet one. The second video is very sad to me, the guy is so convinced with how his students act, that he believes he could use that stuff in a fight...
So let me set some things straight first...A) I've only been practicing the internal arts for 5 years and am very much a beginner even though I hold a first degree black sash. and B) I also happen to be a practitioner and believer in real energy work.
However I would never be one to claim to use nothing but energy and mind in a fight nor push over stones. I really don't care to go into great detail about magic and mysticism here as it really holds no value to the conversation nor is it the topic at hand. However for those interested, please let me know...
As to Qi, the way I was taught by my sifu, Qi does not leave the body. Now a lot of people argue this, I also do spiritual healing and others claim to use qi to heal by projecting it. This does sit with my martial arts training. I think it's a case of bad translations and assumptions. The Chinese philosophies and practices of energy work when applied to martial arts is a bit much to go into a lecture. However I'll share some of the elementary level concepts when it comes to martial arts and internal cultivations. It's actually argued that westerns will never fully understand as we have to different of a culture.
A person is composed of 3 energies and 7 souls (taoist practice) the 3 energies are relevant here. Jing, Qi and Shen. Jing is your body it's self, your physical substance, qi is your internal energy your intent, it's what moves your body. Shen is your spirit this is what leaves and projects from your body. I once heard it described as a candle, the wick and wax is your Jing, the flame is Qi and the light and heat are Shen. As internal practitioners, we cultivate our jing and qi to produce shen. though there are some (not my sifu) who utilize Shen for healing and the like, it's on an ethric and ethereal level. This affects the physical, but only by reflecting to the physical just like a physical injury will reflect on us spiritually and mentally. However, I like many separate physical from spiritual. You handle physical with physical and spiritual with spiritual. Even though they influence and help each other, consider the issue at hand. Qi for example, is utilized for the movements in taijiquan. It's the intent and where our raw power comes from. it's the key ingredient in fajin, explosive power. As my sifu says "with out qi there is no taiji"
sinking and ground with our minds, directs the qi and makes us more stable. (in magic practice separate from martial arts we have a saying "all energy follows thought"). We put our intent there and it is so. The idea during pushing hands and even combat is to uproot the opponent and break his grounding. However I have seen or heard of anyone successfully doing this with out physical contact. I will say from my own personal experience that putting your intent your qi behind it and doing brother breathing and the cultivation and qigong exercises have made me MUCH MUCH better and the techniques are more effective.
I respect anyone's opinion to disagree, and I dont' speak for all internal CMA guys. At the same time please don't lump us all in with these videos here. Heck I know I'm a bit out there myself, and know others dont' want to be lumped with me or my crazy ideas. However it's my path and to each their own.
