Ann Ree Colton's vast knowledge of the inner life is conveyed with an enthusiastic clarity and logic as she describes the nature and function of the ego, the undersoul, the Higher Self, the Most High Soul, and man's hierarchy nature. The greater unconscious and its complement, the collective unconscious, are revealed to contain the blueprints of things to come. Movement and conscience are necessary to cleanse the subconscious and the Undersoul, loosen the egotistical shell, and activate the "Third Music," "Esse," or Holy Spirit in one's being. A section on the practice of Marking and Tracing, or observing oneself and identifying one's negative and positive attributes, presents valuable information for self-improvement and soul-evolvement. Intentional Suffering, hierarchy nature healing, and mastery through the mandala are also discussed. Healing practices and exercises are included.
