IMO, many of these healers are making money from people's ignorance, just like big pharma and the whole of mainstream medicine, and quite a bit of alternative medicine. I prefer to use my own power, energy and knowledge to work out what ails me, its called being self aware, and it comes free from me to me. Its a great way to cut out the middle man.
I know a woman who is always sick, tired and unhealthy, she tells me she can't understand why this is, and doesn't know what is wrong with her. I asked her about her diet, her relationships, her lifestyle and her stress level. She told me that all these things were terrible, I suggested to her that she had just answered her own questions on why she was always sick, tired and unhealthy. Damn it, could have charged her a fortune to tell her what she already knows.
