Yes martial arts are beautiful and elegant and I have always been interested in this. Only recently I started practicing krav maga, perhaps it's not super elegant and it's more about "knock your opponent out quickly and eliminate the threat" but still very fun.
I don't really know how to explain this to be honest but it's more like coming from my feet, through my leg and arm and then into my fist. And I move as I feel this flow. Strange thing is that now, when I started to analyse how to do this I could just barely control this flow I guess It's difficult to analyze and put into words.
You just have to "feel the force flow through you" ,well kind of
Oh, I have one more thing. I think I can heal with energy. If I want to I can make energy come out from my right hand( I think used my right hand the most) and it's different than the punch. If I do this on myself It will lower the pain for example - I am not sure it could be placebo or something though. But at the same time I did this on my dog and I think it helped too. I could feel her stomach ache less. So either I am going crazy or I can actually heal!
