Essentially the metaphysical technique is a means of directing the body to become more receptive to healing. Relaxation, visualization, and affirmation draw upon the power of the mind to activate the body's vibrations to correspond to those of a particular colour.

Once the mind taps into a holistic awareness of a colour, the body begins to respond accordingly. So whether the eyes see it or the mind only visualizes it, the perceived colour elicits a physical attuning of vibrations to effect healing.

This might bring up the question of which is the better approach to colour therapy , filtered rays upon the body, or the metaphysical technique. There can be no definitive answer, because too many variables are called into question, including the fact that the same illness in two different persons may arise from different causes, thus requiring different kinds of treatments to eliminate the origins.

No therapeutic method should be presumed superior to another, since the best for anyone is the one that works for that person. As far as colour therapy is concerned, perhaps the two methods ' light and metaphysical ' might be applied simultaneously to expedite the healing process. The mind, at any rate, plays a vital role in healing ' no doubt as important a role as the therapy itself.

Spirit is the life, mind is the builder, the physical is the result. But the mind can also operate destructively and bring illness to the body by allowing attitudes and emotion to usurp healthy vibrations. When the body falls prey to sickness, the mind is never totally blameless. Nor is it exempt altogether from the healing process. But exactly what is healing? At the most elemental level, we should:

Know that all strength, all healing of every nature, is the changing of vibrations from within  the attuning to the divine within the living tissue of a body to Creative Energies. This alone is healing. Whether it is accomplished by the use of drugs, the knife, or whatnot, it is the attuning of the atomic structure of the living cellular force to its spiritual heritage. (1967-1)

Colours are from the fundamental forces of vibration as they apply to the material forces magnified in the physical world. It is through these forces that healing comes to us from the Divine, the source of Universal supply. It is also through these forces that we may channel healing vibrations to others. For this purpose, vibration is the raising of the Christ Consciousness in oneself to such an extent that it flows out to whomever it is directed.
