We have seen that the possible field of consciousness is limited by the sanskaras. This limitation creates a division of the human psyche into two parts. One part falls within the range of consciousness, and the other part falls beyond it. The unconscious part, in its full extent, is identical with the power that is behind matter. It is referred to as God by the orthodox religions. The ultimate Reality, which is symbolically represented through such concepts, can be known fully only by bringing the unconscious into consciousness. An extension of consciousness consists in being conscious of that which was formerly a part of the unconscious. The progressive conquest of the unconscious by the conscious culminates in consummate consciousness, which is unlimited in scope and unhindered in function. Between this highest state of consciousness and the limited-though full-consciousness of average humanity, there are about forty-nine degrees of illumined consciousness. They mark the important stages of growing Illumination.
