The Hermetic Masters long since discovered that while the Principal of Rhythm was invariable, and ever in evidence in mental phenomena, still there were two planes of its manifestation so far as mental phenomena are concerned.
They discovered that there were two general planes of Consciousness, the Lower and the Higher, the understanding of which fact enabled them to rise to the higher place and thus escape the swing of the Rhythmic pendulum which manifested in the lower plane. In other words, the swing of the pendulum occurred on the Unconscious Plane and the Consciousness was not affected. This they call the Law of Neutralization. Its operations consist in the raising of the Ego above the vibrations of the Unconscious Plane of mental activity, so that the negative-swing of the pendulum is not manifested in consciousness, and therefore they are not affected. It is akin to rising above a thing and letting it pass beneath you. The Hermetic Master, or advanced student, polarized themselves at the desired pole, and by a process akin to “refusing” to participate in the backward swing, or, if you prefer, a “denial” of its influence over him, he stands firm in his polarized position, and allows the mental pendulum to swing back along the unconscious plane. All individuals that have attained any degree of self-mastery, accomplish this, more or less unknowingly, and by refusing to allow their moods and negative mental states to affect them, they apply the Law of Neutralization. The Master however carries this to a much higher degree of proficiency, and by the use of his Will he attains a degree of Poise and Mental Firmness almost impossible of belief on the part of those who allow themselves to be swung backward and forward by the mental pendulum of moods and feelings.
