While pain is a subjective experience, it has neurophysiological, cogn
itive, and emotional substrates in variable combinations. The mind (se
at of consciousness, thought, volition, and feeling) can exert a power
ful influence over both our experiences and our bodily functions. The
author explores the mysteries of modification of pain and bodily funct
ion through rituals and ceremonies, and reviews current status of scie
ntific knowledge concerning the nature and influence of altered states
of consciousness on pain perception and the influences of the placebo
effect in Western medicine. The author concludes that the borders of
mind and body are inextricably intertwined and that if properly used,
the placebo effect can be therapeutic.
