i do belive in chi/ki but in the forms of what dbz and naurto make it out i dont belive we can create ki blasts ect using the engry of our bodys, and i also dont belive that strength is what wins fights ect because you may have the muscles and that but what would those muscles be without the use of though. You could be the size of triple H and so on but i have seen ppl who are not that big who use thier mind to their full capatiblty and just make the other guy look like a weaklend, to me it all comes down to if you have power you need brains to go with it otherwise you will just be a huge target. now with the fighting bit done to me chi/ki is a state of mind where u are in peace ie not a though in your head and your body is releaxed dont get me wrong i dont see sleeping a form of using ur chi as ur mind is still thinking and creating ur dreams. i hope i made sense lol but yes that what chi/ki means to me
