spiritual combative capability would carry over, but i don't think physical would.
i am not saying this from direct experience, but from what others have said the way the astral works is different from how it works here. there, you intend to do something, you will it to happen. here, you send the right signals to your body, you just do it.

does anyone have any knowledge about whether skills from the physical would carry over into the planes or not? would martial arts training here have an effect there?
