A very common idea within the world of self-help is that sickness is merely an external expression of negative states of mind.
The virus, the bacteria, the inherited illness - all are bunkum in the world of self-help, where one's unfortunate physical circumstances can only ever be evidence of wrong thinking.
This is a very old idea, and, like many popular self-help ideas, can be traced back to the work of Phineas Parkhurst Quimby, a faith healer who inspired the work of Mary Baker Eddy and many others.
The concept is still going strong - kept alive in the 80s and 90s through the work of Louise L. Hay, some Australia authors also subscribe to this system of ideas, most notably Annette Noontil and Inna Segal. In most of these books one can look up the symptoms of one's illness and discover the corresponding mental or spiritual causes. Then there is normally a suggested cure, taking the shape of an affirmation or prayer or visualisation which will reverse the negative state that caused the trouble. Such a system seems to be very comforting to those who are ill - probably quite understandable when one considers how alienating and authoritarian the conventional medical system can be.
I'm very interested in Inna Segal's work because she is quite young and the book (The Secret Language of Your Body) has been released quite recently. It intrigues me how she managed to learn and absorb these old ideas. I can see the strong influence of New Thought and Christian Science teachings in the work.
But, on a purely practical level I have to report that a chronic health condition I was suffering from last year remained completely unaffected even though I scrupulously applied these 'esoteric healing' methods. Eventually the only cure was good old fashioned surgery.
