I've heard many doctors refer to themselves as "healers," as if we have some special power to bring about healing in our patients. This idea confers some sort of a higher status and originates, to some, from a "higher calling" to a more noble life. Again, this is a logical step, in that we have opportunities on a regular basis to help and even save the lives of people. It's natural to believe that somehow the healing power comes from our touch, or even from our knowledge.
It doesn't. I am not a healer.
