How does Transcndental Mediation compare with other forms of mediation?

A meta-analysis of 597 studies of meditation practices was published in the American Journal of Health Promotion (May/June 1998). The study found the Transcendental Meditation technique to be significantly superior to other forms of meditation and relaxation in a wide range of criteria related to mental and physical health.Another meta-analysis, published in the Journal of Social Behavior and Personality, found the effect of the Transcendental Meditation technique on increasing self-actualization to be markedly greater than that of other forms of meditation and relaxation.
