Healing is certainly real, I know, I do it. Hello everyone my name is Shads and I'm a spiritual healer. There I said it my guilty secret is out.
It's hard to explain how it works and I prefer the term "energy healing" as it's nothing to do with spirits in the form that I do it, and I suspect in all forms, but it is to do with manilpulating another person's energy from outside, even at a distance which is the form I'm best at. It's not a guaranteed result, you don't even have to believe in it to receive it but it really does work.
Psychic Surgery I believe works in a very similar way but I can't explain that as I've never been taught how to do it. Very strong Kinetics (I've met one) can move another person's body parts around and even at the top end of the ability, destroy a cancer, gall stone or other such thing from outside the body. I can't vouch for them who say they take out the problem through the skin, as I've never had that proved and actually doubt that myself.
The one's who have been proven to be charlatans are individuals, and proving an individual wrong is not proving the whole thing wrong. I myself have healed torn muscles over MSN, have taken a migraine away (that was hard and I ended up with a headache myself instead), helped someone with IBS, and I tend to heal quicker than most people with minor things... oh and I don't burn easily... I mean I caught my hand on an iron last weekend and it tingled a little, it didn't burn though.
Healers have major problems healing themselves though, no idea why, might be something to do with energy flows.
I had a major problem myself healed by a Shaman who I became friends with. I went to him to ask him to tell my fortune, I was fed up and have had it done before, but he refused. He said he didn't want to tell me what was in store for me, he wanted to heal me instead. I was very sceptical but went along and 3 weeks later I was feeling much better. I don't want to go over what he healed, it'd take too long to explain anyway, but my doctor was amazed.
It does exist, you can't prove something doesn't exist by it's abscence, you can only prove doubt in it's existance. I believe you could prove a bumble bee can't fly using physics, and I believe that you can prove many things using known laws that are untrue. Healing works through unknown laws... what people like to label "magic". Magic is merely a process we don't understand yet. To me a TV is magic but energy healing isn't. Maybe to you it's the other way round.
