few are trained in the dark arts....Hehe just kidding...-
actually, i just thought about that today. i was thinking, that i often think about getting in fights with someone that knows some martial arts(kindof happened when i had some sparring competition with a very good wrestler), but what if i meet a really good martial artist and we have some disaggreements..
one thing is that really good martial artists are often smart people that dont get into fights that easily. unless they are a little crazy like myself and lacking some braincells. bottom line is that all people, especially violent offenders, know some martial arts..
also, people that are really secure and truly spiritually(psychologically) strong individuals also are not really that aggressive. people with problems and issues can be. but for physical violence, anyone can be destructive and dangerous in different ways.
this is probably a great mystery in the martial arts as well as in life generally. but aggression and violent intent cannot be avoided. physical techniques can be avoided to some degree, but aggression and violence must be dealt with. processed in an efficient way. this doesnt only apply to physical fighting but all communication.
conversely_#, physical threats cannot be ignored without compromising security.
most of this sort of communication, body language is very instinctual but it can be trained in various ways. these ways are very hard to describe without causing confusion. but the main subjects are the training of the tanden(key words-zazen,yoga,chigung) to achieve a powerful psyche and nervous system as well as certain rules of motion, politeness and interpretation of body language to discern the meaning of motion and stillness-closeness and distance-light and dark. above that, also vital is the training of the spirit to understand mercy and benevolance. because the greatest friend or enemy you can have, is your own conscience.
that is a system that has literaly worked wonders for me.
