(16) I. The Principle of Correspondence The Principle of Correspondence manifests in a certain correspondence or analogy or agreement between manifestations of the various planes of activity in the Cosmos. It is indicated by the old Hermetic aphorism: "As above, so below; as below, so above," and by the Arcane axiom: "Ex Uno disce Omnes," or "From One know All." The Rosicrucians, and other ancient occultists, hold that the laws governing the nature and activity of the amoeba, likewise govern the nature and activity of man and beings higher than man. What is true of matter is true of energy and of mind. The occultists make a practical application of this universal principle, in the direction of studying the unknown by means of the known, with the knowledge that the same laws govern each. Thus, just as the solar system may be known by means of studying the atoms and molecules, so may the higher planes of being be studied by an examination of the lower planes in manifestation before us.

(18) A writer has said of this Cosmic Principle: "There is always a correspondence between the laws and phenomena of the various planes of life and being. The grasping of this truth gives one the means of solving many a dark paradox, many a hidden secret of Nature. There are planes beyond our knowing, but when we apply the Principle of Correspondence to them we are able to understand much that otherwise would be unknowable to us. This principle is of universal application and manifestation, on the various planes of the material, mental and spiritual universe—it is an universal law. The ancient Hermetists considered this principle as one of the most important mental instruments by which man was able to pry aside the obstructions which hid from view the Unknown. Its use even tore aside the Veil of Isis to the extent that a glimpse of the face of the goddess might be caught. Just as a knowledge of the principles of Geometry enables a man to measure distant suns and their movements, while seated in an observatory, so a knowledge of the Principle of Correspondence enables man to reason intelligently from the Known to the Unknown. Studying the moneron, he understands the archangel.

(17) After discovering the operation of certain principles in one thing we may safely reason by analogy based upon the assumption that these principles exist in other things on a higher plane, and thus discover the nature of the unknown " x ." Thus the occultist reasons that there is Law and Order manifest on every plane of being; that there is a Principle of Vibration manifest on every plane of being; that there is a Principle of Rhythm manifest on every plane of being; that there is a Principle of Cycles manifest on every plane of being; that there is a Principle of Polarity manifest on every plane of being; that there is a Principle of Sex manifest on every plane of being. And the further that human investigation is pushed into the Unknown, the greater is the proof of the existence of these Cosmic Principles reasoned out by the ancient occultists upon the fundamental basis of the Principle of Correspondence.

(38) A writer has said of this: "The Ego may convert the circle of its life-motion into an advancing and rising spiral, which while carrying him around the life circle will at the same time raise him a stage higher at each turn. The Mountain of Attainment, around which winds the Spiral Path, is travelled only in this way. Around and around the Pilgrims travel, seemingly retracing their steps but in reality constantly mounting upward. By advancing the Central Point, by means of the Will , the wise and the strong convert the Circles into Spirals, and thus advance and attain. This, indeed, as the old aphorism states, 'is one of the highest forms of Mental Alchemy.'" The further the student penetrates in his investigations, along the lines of the physical, the mental, or the spiritual, the more will he become convinced of the truth of the ancient occult axiom that "Everything proceeds in circles." VI. The Principle of Polarity The Principle of Polarity manifests that universal fact of "the pairs of opposites," or "the antinomies," which is apparent in all the manifested world, from its highest to its lowest manifestation. The spirit of this principle was expressed in the ancient occult axiom: "Everything has its Opposite, which is the other pole of its manifestation." The Principle of Polarity may be stated as follows: "All phenomena manifest polarity, or opposite and contrasted sets of qualities, properties, or powers, operating in opposite and contrasted directions." The ancient philosophers made this one of the chief features of their teachings, under the name of "The Opposites," "The Pairs of Opposites," or "The Antinomies," according to the usage of the respective schools. They held that every phenomenal thing possesses and manifests these pairs of opposite qualities, properties, and powers. They also held that each and every set of polarized opposites constitutes a unity consisting of a reconciliation and balancing of the opposing poles. They also held that every phenomenal thing, itself, is one of a pair of polarized opposites which, together, constitute a greater unity; and so on, either to infinity or until the opposites find final reconciliation and harmony in an Infinite Reality.

(19) Without going deeply into the matter of the application of this particular Cosmic Principle, we may say that one of the fundamental facts of being discovered by the ancient occultists by the application of the said principle is this: That in every thing there is to be found (1) Substance, or Body; (2) Motion or Active Energy; and (3) Consciousness or Awareness. Therefore, when dealing with planes of being of which, at the time, they had but little knowledge, the ancient occultists always assumed the existence in everything on the unknown plane of these three great forms of manifestation. And all future esoteric investigation and discovery tended to disclose facts corroborating and sustaining the original assumption derived by analogy, and the discoveries of modern science have invariably tended in the same direction.

(30) That which is true in the superior is true in the inferior. If alchemy be a great spiritual fact, then it is also a great material fact. If it can take place in the universe, it can take place in man; if it can take place in man, it can take place in the plants and minerals. If one thing in the universe grows, then everything in the universe grows. If one thing can be multiplied, then all things can be multiplied, "for the superior agrees with the inferior and the inferior agrees with the superior." But as the way for the redemption of the soul is concealed by the Mysteries, so the secrets for the redemption of the metals are also concealed, that they may not fall into the hands of the profane and thereby become perverted.
