I'll say right off that I don't know much more than you, but I've heard it said that there are "hard" and "soft" forms of martial arts. Karate is hard, Akido is soft. There are also "internal" martial arts, like qigong. I practice chi-lel qigong almost everyday and get a lot out of it. The closest thing to it out of those forms you mentioned would be tai chi. If you're interested, type chilel into a search engine and it should take you to the official site, where they list teachers around the country. Sorry I can't be of more help.
