Meditation: a new role for an old friend.

Meditation has been a spiritual and healing tradition for centuries. In 1972, Keith Wallace and Herbert Benson published a landmark article looking at meditation from a scientific perspective. The author reviewed their article, plus selected scientific literature on meditation since that time, to see if there was enough evidence to warrant the inclusion of meditation in the treatment protocols of serious disease. This review, plus an illustrative case study, demonstrated that such inclusion is warranted and further research is necessary.
