This is a subject that piqued my interest but, about which, nothing useful seems to have been written. I've been able to find lots of testimonials about quantum healing for back pain and I watched one story on Youtube about a hospital in China that uses no medicine and showed some practitioners causing a tumor to vanish in a few minutes. When I asked questions to the people who present this information about using the same techniques with autism, they either don't answer or they referred me elsewhere where I again found no answers.
Some of these methods insist that the patient heals himself and all the practitioner does is to direct energy to them. The body then knows what to do with that energy to heal itself. If that's true, it only makes sense that the same energy directed into an autistic person should result in the body being able to undo the damage caused by mercury that created the autism.
I did discover a couple of sites that alleged to use this sort of healing to address autism as a case of poor wiring so I didn't bother reading any further. Neither one of them looked very useful though.
This site wants to sell you lessons on how to perform quantum healing. You can glean some more information without paying them by watching their videos and reading their forum. I think they're legitimate.
A different site teaches you how to use energy with chakras and the pineal gland in a manner that I think is worth watching. Here's the site for Rama, the teacher in the above group of videos. He discusses some interesting things but autism is not one of them. Nevertheless, I feel what he has to teach is useful and may prove useful to autistic people.
Breathing techniques are important in dealing with acquiring and transferring unseen energy. One that is similar to what Richard Gordon discusses on his Quantum Touch site is about the same as was discussed by the Wingmakers called the Quantum Pause. There are some good discussions about breathing techniques here.
I don't pretend to be any sort of expert on anything I've brought up here but I have been able to tap into some of this energy and did achieve some successes in this area. I don't know if this will work for autism but I am looking into it. I have tried it briefly with my son and have seen some evidence that makes me think it will be useful. I'd appreciate links and discussion to any more knowledge that might help us use this to help autistic kids.
UPDATE 6/17/12: Since I wrote the above, my son has said "Daddy" three times, the first time he has said this in his 15 years and the first time he has ever repeated any word.
