Patrick D. Miller, the first publisher of Gary Renard’s Disappearance of the Universe book, wrote an excellent article on how he used principles from A Course in Miracles to heal himself:
I was 32 when I was struck with a mysterious new illness, then just being noticed nationwide, that would soon be called Chronic Fatigue Syndrome (CFS). I’ve reported on that experience in detail elsewhere, so I won’t reprise the whole story here. It suffices to say that I exhausted multiple medical approaches, including alternatives such as acupuncture, crystal healing, and desperate wishing before I grudgingly accepted the possibility that the sudden onset of chaos in my body might have something to do with the long-standing miasma of my mind. That realization led to about nine weeks of psychotherapy and, during that same period, the discovery of A Course in Miracles.
