Well to yield the results you are talking about...the same as is seen culture to culture....it should start to ring some bells that it is the same basics. The same ones the Indian and Chinese wrote about, and Ueshiba quoted!
Then we have to ask.....
Why can't everyone do it? It's a basic?
Or was it on purpose?
Thankfully there are those willing to do the job others can't or won't.
Even though it is my own post this rang a bell for a further thought.
Why can't everyone do this stuff?
It's basic....yet shodan to Shihan...you can't do it.
The answer and the solution, should unite us in friendship, not divide us.
