Biofeedback
The third consciousness altering methodology which will be briefly described is biofeedback. Biofeedback is somewhat unique in that it actually employs the self-cognitive powers of the left hemisphere to gain access to such areas of the right brain as the lower cerebral, motor and sensory cortices and assorted pain or pleasure centers. Instead of suppressing the left hemisphere as is done in hypnosis, or largely bypassing and ignoring it as is done in transcendental meditation, biofeedback teaches the left hemisphere first to visualize the desired result and then to recognize the feelings associated with the experience of successful right hemisphere access to the specific lower cerebral, cortex, pain or pleasure or other areas in the manner needed to produce the desired result. Special self-monitoring devices such as the digital thermometer are used to inform the left brain when it succeeds in keying the right hemisphere into accessing the appropriate area. Once this is done, the left brain can then repeatedly instruct the right brain to reestablish the pathways involved so as to produce the same external, objective measures of success. In this way, the pathways are strengthened and emphasized to such an extent that left brain consciousness is enabled to access appropriate areas in the right brain using a conscious, demand mode.
For example, if the subject wishes to increase the circulation in the left leg in order to speed up healing he may concentrate with his left brain on achieving that result while carefully monitoring a digital thermometer connected to the left leg. When the concentrated effort begins to achieve success, the digital thermometer will register an increase in the temperature of the left leg. At that point, the subject can mentally (left brain) associate the sensations experienced with the result achieved and can begin to emphasize, by memory recall, the same process to cause its strengthening by affirmation and repetition. in this way, pain can be blocked, healing can be enhanced, malignant tumors can apparently be suppressed and ultimately destroyed, the body’s pleasure centers can be stimulated, and a variety of specific physiological results may be achieved.
In addition, biofeedback may be used to greatly accelerate achievement of deep meditative states particularly for beginners who have no experience in meditative techniques and whose progress in that methodology is enhanced through effective visualization and external, objective affirmation. Display of the subject’s brainwave pattern on a cathode ray tube has proven to be a laboratory-validated means by which subjects may quickly learn to place themselves in profoundly relaxed states characterized by the sort of quietude and singularity of mental focus associated with advanced meditation.
Transcendental Meditation
On the other hand, transcendental meditation works in a distinctly different fashion. In this technique, intense and protracted single minded concentration on the process of drawing energy up the spinal cord ultimately results in what appears to be creation of acoustical standing waves in the cerebral ventricles which are then conducted to the gray matter in the cerebral cortex on the right side of the brain. As a result, according to Bentov, these waves “will stimulate and eventually ‘polarize’ the cortex in such a way that it will tend to conduct a signal along the homunculus, starting from the toes and on up.”
Gateway and Hemi-Sync
Now that we have briefly profiled the basic mechanics of the principal techniques for altering or expanding consciousness which share some of the objectives and/or methods employed in the Gateway Experience, we may proceed to focus on what that technique actually involves. Fundamentally, the Gateway Experience is a training system designed to bring enhanced strength, focus and coherence to the amplitude and frequency of brainwave output between the left and right hemispheres so as to alter consciousness, moving it outside the physical sphere so as to ultimately escape even the restrictions of time and space. The participant then gains access to the various levels of intuitive knowledge which the universe offers. What differentiates the Gateway Experience from forms of meditation is its use of the Hemi-Sync technique which is defined in a monograph by Monroe Institute trainer Melissa Jager as, “a state of consciousness defined when the EEG patterns of both hemispheres are simultaneously equal in amplitude and frequency.”
