These other arts are certainly worthy of study, but I cannot discuss that with which I am not familiar. Many Oriental martial arts are Ways, as in way of life or way of thinking. These are not just fighting systems. They are fighting systems and systems of ethics and correct behavior. Body and character are trained together.
Some fighting systems are just that.
In Japan, these are suffixed - jutsu to show that they are arts like boxing and wrestling where character training is derived from physical training. Jujutsu is such an art. We in the west have an unfortunate tendency to compartmentalize our skills. We consider our philosophy and our physical selves to be separate. Too many think that the mind can be trained without the body and vice versa.
