Hi I have one question. I train Go Ju Ryu karate for several years but I Have one question. I heard that karate can be trainded in more "psychic power way" where you can "feel" energy. And i want to know more about it, but i heard that this type of karate can have psychic consequences and you can go crazy(simple it is wery hard on physic). Do You know what i Mean and do you know something more?
