The power of Theta and Delta waves – Experiments

“Experimental evidence of the existence of a fourth state of unified, transcendental consciousness,  at the transition between sensory and sleep consciousness, was first recorded at the Menninger Foundation in Kansas, United States in 1971.[6] Under the direction of Dr. Elmer Green, researchers used anelectroencephalograph to record the brainwave activity of an Indian yogi, Swami Rama, while he progressively relaxed his entire physical, mental and emotional structure through the practice of meditation.What they recorded was a revelation to the scientific community.[cit
