Re: Cultivating a mind for training honestly.
I think first you have to establish control of yourself to a degree, at least philosophically. I think you need to be in control enough of what matters to affect the situation.
I think (and know) that it is possible to affect and control others both physically and mentally. We do it all the time, and allow others to do it to us as well.
While we are striving for self mastery in which we no longer allow others to control our minds, our physical bodies I think are a different story all together. A good read on the subject is Victor Frankl.
