Physiological Indicators of Deep Rest
A meta-analysis, the preferred scientific procedure for drawing definitive conclusions from large bodies of research, found Transcendental Meditation produced a significant increase in basal skin resistance compared to eyes-closed rest, indicating profound relaxation.
Deep rest and relaxation were also indicated by greater decreases in respiration rates and plasma lactate levels compared to ordinary rest. These physiological changes occur spontaneously as the mind effortlessly settles to the state of restful alertness, pure consciousness.
