Research from the last 55 years shows that Transcendental Meditation practise produces a unique physiological state where the body experiences deep rest while the mind is alert.
This state is characterised by a sharp decrease in the respiratory rate, increased blood flow to the brain, and an increase in brain orderliness and integration. Indicating a reduction in stress, we also observe changes such as decreased cortisol, deep muscle relaxation, reduced arterial blood lactate, and increased galvanic skin response.
Researchers have concluded that the TM technique produces a fourth major state of consciousness, Transcendental Consciousness, a state of restful alertness, which is distinct from waking, sleeping, and dreaming. This state is unique to TM practise.
