There are several ways to go about this Skyz. But first and foremost you must acquire the belief that your mind is an amazing healing organ. Think of what happens when you get a simple cut from a knife. The body heals itself without your help at all! So what if you harnessed that ability and took charge of it and actually helped it along?
I personally use two methods: one is a self-healing meditation that basically relaxes your body into a state of self-hypnosis, which allows the ego to shut up and opens the mind to suggestion. While in this state you become an energy sponge, bringing in healing light to your body as a whole or directed to any particular spot you want. Obviously this technique is not something I can teach you in a forum but if you spend some time on You Tube and search for "healing meditations" try and few of them out and see what works best for you. I've used the same one for years and I think it's available on iTunes. I'll send a link if I can find it.
The second thing I do is I talk to my brain. I say, "Stop making my knee hurt" or say I might be getting a scratchy throat I say, "go down there and take care of that." You believe you have this power and you are basically directing your body to do something in a firm and loving way. Once again, the belief that you have the power to do this is the most important aspect. I've told my friends this time and time again over the years and they're like, 'yeah, yeah, sure." Now that they've known me for say 20 years they are asking, "How come you're never sick?" This is what all this New Earth stuff is about, people are waking up and asking these questions and people like me are ready with the answers, just like you are ready with your answers to things you have been dealing with for a long time.
There is a particular book that helped me when I was healing a terminal disease I had in 1990 and was trying to learn about all this. It's a book called Healing Back Pain by Dr. John Sarno. It talks about back pain, but the technique applies to any disease or chronic condition. He was an orthopedic surgeon who discovered that most of his patients who suffered chronic things, it was because of thoughts they had: fear, anger, resentment, etc. So he stopped doing surgery and started treated people's thoughts. After many years of this he found that only about 10% of people are able to accept that their mind was actually doing this, so he would only work with these people. The reason the mind was doing this "to" them is that whatever thought they were having was so intense (or buried) that the mind said, "Here, let me give you this pain (or disease) to focus on instead of that painful emotion." Once a person addressed whatever the thought problem was, the pain went away immediately. And I"m talking immediately. So, once you get this, you can apply it to anything. Now people get injured, they break an arm or something, and that requires some professional treatment, but the actual healing process is done by the body. Take charge of your mind, take charge of your health. It's a very simple concept but it's not so simple for many people to accept and do.
