Re: hips and shoulders
Just been doing some more research into Koshi. I usually do it this way funnily enough in that I use a principle and develop it, (or rather develop myself on it) then when I know how pertinent it is I go look it up for by then I know someone somewhere must be using it and that it has history.
The way I have described it I find more on via the web now and the spiritual aspect as I describe I find there in the annuls of okinawa karate and even the flag. Fascinating.
It's all good.
