I do not think about the second way of thinking as a possibility.
1)How do they know so surely that they can help him, that his healing is certain? Is this some kind of failproof treatment, cause I could believe that it can help some people, but to believe that it works in each and every case I cannot believe.
2)That is how you start a healing treatment? Putting the patient in financial stress? Everybody knows that higher than normal stress makes people sick, and also high stress is a hindrance in someone's healing. I thought that this method is based on the theory that when you relief body from the stress, the body knows itself how to find its way back to its former state of health and optimum functioning. Aren't those exercises meant to restore the healthy flow of energy in the body, which is blocked by stress or other factors? Aren't those exercises meant to be made with the conscious too, with the mind, as the essential part that makes them different to some kind of "verrrrrry slow easy aerobic"? Where was the mind of the guy was most likely going to be? At the movements he was supposed to do, or to the financial debt, wandering all the time whether these exercises helped him for the day and they were worth getting into debt for, or they did not work and it was a stupid financial move to borrow money?
If they were so concerned about his health, they would have offered him lessons for free. I am sure they would have survived without his money just the same, and when you are practicing a healing treatment that puts big emphasis on the spirit, I would expect from such people to be more "spiritually evolved" and not be linked so much to the "material side" (money!!!!!)
