There are many miracle healer scammers so here is an article about legitimate miracle healers. The healer I saw was asked to become a healer by one of the healers mentioned.
I like how Adam the Dream Healer, one of the healers mentioned, has a website as a gathering place for others to focus their intentions on healing those afflicted with certain diseases. I also think it is helpful that he is studying molecular biology and biochemistry- so he might know more specifics what is happening is body. He'll pick a particular disease, say diabetes, and have everyone focus their energy on healing those with that particular illness at a specific time of the day. I think I will request him to focus his energy on people with EC. The video link below explains how energy healing works with Adam the Dream Healer.
