what evidence is there of the effectiveness of spiritual healing?
At the moment this is largely anecdotal, although experiments have been carried out that show that those that have received spiritual healing recover more quickly, and more completely, than those who have not. To suggest that spiritual healing cannot exist because it cannot be measured by current instrumentation does not, for me, stand up. Ironically quantum physicists do not have a problem with the concept of energy transfer as it occurs with distant healing as it is in accordance with their calculations. I am sure that in the next decade or two the energy will be capable of being measured. On a personal level I have no doubt about its effectiveness.
