Why meditation
1. Why meditation?
BACKGROUND While many general practitioners perceive meditation as an acceptable, even
mainstream, health care strategy, it is paradoxically a poorly understood discipline.
OBJECTIVE To define meditation, outline the broad types of meditation and give an overview of the
extent and validity of available evidence for its efficacy.
DISCUSSION The basic question of what constitutes meditation and what separates it from relaxation
therapy has been an impediment to formulating quality studies in order to research meditation
techniques. Examining the literature using evidence based criteria reveals that, while meditation does
appear to have therapeutic potential, there is a great need for further research before definitive
conclusions can be made. Researchers have yet to systematically compare different techniques of
meditation to compare their profiles.
