One of my interests is energy medicine. I have explored various approaches. The ones I currently find most interesting are Zdenko Domancic Bioenergy Therapy and the work of Donna Eden which is based on Touch For Health which has procedures for testing and balancing the 14 primary Chinese medicine (TCM) meridians.
This morning, I was looking at a book called "Vibrational Medicine: The #1 Handbook of Subtle-Energy Therapies", by Richard Gerber, MD. There is a chapter in this book about scientific studies that have been done with persons who describe themselves as spiritual healers. These studies show that, even from a distance, such persons can have a positive effect on plants, animals, and water, and that, in general, the effects are always towards life, health, and improvement, and away from entropy. One of the studies suggested that anyone could learn to do this kind of work and that effectiveness seemed to improve with practice.
