I went through a serious, long-term degenerative illness-severe chronic pain and other physical symptoms that doctors couldn't pinpoint the cause of. I was healed completely by practicing SFQ, but only after my faith was SEVERELY tested. In retrospect I'm glad I went through the experience, but I definitely didn't feel that way at the time. I learned that mind rules matter, period. The experience transformed me from an atheist and skeptic (even though I meditated daily) into a complete believer. Most of the pain went away in one day! At one point near the end I thought there was a good chance I would die soon (I was 25 years old at the time) and I said to God/the universe that I wanted to be happy and free of pain, even if it meant giving up my physical body. Of course that didn't happen, but I was willing to accept it at the time (I had come to believe in a soul and afterlife by then). I hope this helps you in some way.
