Welcome to A2K, Unforgiven. It is a pleasure to have you here.
"I'm interested to hear everyone's thoughts on what limitations the mind sets for the body."
This part of your post is what captured my attention the most. I personally would be interested in knowing how limitLESS the mind can be over ones body.
In my own opinion, and it is just that, the mind is an incredible tool, that some have learned to use very well, as in your example of martial arts. I think most others though take that tool and just let it run its own path over the course of their lifetimes.
I think it is a choice, either consciously or unconsciously that we all make about how we use our brains and in what way we use them. We have all heard of the power of prayer in overcoming illness, the will to survive when all odds are against us Tapping into what I believe is unlimited potential of the brain is not limited to physical feats alone. I use the mind over matter technique quite often by talking myself out of a cold that I feel coming on, using the power of meditation to ease the pain of an excruciating fibromyalgia pain flare up and I also use my brain a great deal at night during sleep (I call it night school) to problem solve and gain a greater understanding of life in general..
I think one of the neatest stories I ever heard about mind over matter was the story about a man who was in a very severe auto accident and upon arriving in the ER, all of the Doctors and Nurses did not think he would survive and it was shown by the shakes of their heads and their
pre-set attitudes. The man gathered the strength to tell them, "Treat me like I'm going to live, damnit, not like I'm going to die!" And live he did.
In the end, I think we all have the tool...it's what we do with it that makes the difference.
