(2) Air is, therefore, twofold in nature-tangible atmosphere and an intangible, volatile substratum which may be termed spiritual air. Fire is visible and invisible, discernible and indiscernible--a spiritual, ethereal flame manifesting through a material, substantial flame. Carrying the analogy further, water consists of a dense fluid and a potential essence of a fluidic nature. Earth has likewise two essential parts--the lower being fixed, terreous, immobile; the higher, rarefied, mobile, and virtual. The general term elements has been applied to the lower, or physical, phases of these four primary principles, and the name elemental essences to their corresponding invisible, spiritual constitutions. Minerals, plants, animals, and men live in a world composed of the gross side of these four elements, and from various combinations of them construct their living organisms.

(5) In the secret teachings of the Qabbalah it is taught that man's body is enveloped in an ovoid of bubble-like iridescence, which is called the Auric Egg. This is the causal sphere of man. It bears the same relationship to man's physical body that the globe of AIN SOPH bears to Its created universes. In fact, this Auric Egg is the AIN SOPH sphere of the entity called man. In reality, therefore, the supreme consciousness of man is in this aura, which extends in all directions and completely encircles his lower bodies. As the consciousness in the Kosmic Egg is withdrawn into a central point, which is then called God--the Supreme One--so the consciousness in the Auric Egg of man is concentrated, thereby causing the establishment of a point of consciousness called the Ego. As the universes in Nature are formed from powers latent in the Kosmic Egg, so everything used by man in all his incarnations throughout the kingdoms of Nature is drawn from the latent powers within his Auric Egg. Man never passes from this egg; it remains even after death. His births, deaths, and rebirths all take place within it, and it cannot be broken until the lesser day "Be With Us," when mankind--like the universe--is liberated from the Wheel of Necessity.

(50) The ancients conceived the spirit of man to correspond with the color blue, the mind with yellow, and the body with red. Heaven is therefore blue, earth yellow, and hell--or the underworld--red. The fiery condition of the inferno merely symbolizes the nature of the sphere or plane of force of which it is composed. In the Greek Mysteries the irrational sphere was always considered as red, for it represented that condition in which the consciousness is enslaved by the lusts and passions of the lower nature. In India certain of the gods--usually attributes of Vishnu--are depicted with blue skin to signify their divine and supermundane constitution. According to esoteric philosophy, blue is the true and sacred color of the sun. The apparent orange-yellow shade of this orb is the result of its rays being immersed in the substances of the illusionary world.

(13) This vital energy has its origin in the spiritual body of the earth. Every created thing has two bodies, one visible and substantial, the other invisible and transcendent. The latter consists of an ethereal counterpart of the physical form; it constitutes the vehicle of archæus, and may be called a vital body. This etheric shadow sheath is not dissipated by death, but remains until the physical form is entirely disintegrated. These "etheric doubles, "seen around graveyards, have given rise to a belief in ghosts. Being much finer in its substances than the earthly body, the etheric double is far more susceptible to impulses and inharmonies. It is derangements of this astral light body that cause much disease. Paracelsus taught that a person with a morbid mental attitude could poison his own etheric nature, and this infection, diverting the natural flow of vital life force, would later appear as a physical ailment. All plants and minerals have an invisible nature composed of this "archæus," but each manifests it in a different way.

(18) The reader should be careful not to confuse the Nature spirits with the true life waves evolving through the invisible worlds. While the elementals are composed of only one etheric (or atomic) essence, the angels, archangels, and other superior, transcendental entities have composite organisms, consisting of a spiritual nature and a chain of vehicles to express that nature not unlike those of men, but not including the physical body with its attendant limitations.

(15) The Plane of Elemental Mind (A) comprises the state or condition, and degree of mental and vital development of a class of entities unknown to the average man, but recognized to occultists. They are invisible to the ordinary senses of man, but, nevertheless, exist and play their part of the Drama of the Universe. Their degree of intelligence is between that of the mineral and chemical entities on the one hand, and of the entities of the plant kingdom on the other. There are seven subdivisions to this plane, also.

(49) Consciousness, intelligence, and force are fittingly symbolized by the colors blue, yellow, and red. The therapeutic effects of the colors, moreover, are in harmony with this concept, for blue is a fine, soothing, electrical color; yellow, a vitalizing and refining color; and red, an agitating and heat-giving color. It has also been demonstrated that minerals and plants affect the human constitution according to their colors. Thus a yellow flower generally yields a medicine that affects the constitution in a manner similar to yellow light or the musical tone mi. An orange flower will influence in a manner similar to orange light and, being one of the so-called secondary colors, corresponds either to the tone re or to the chord of do and mi.

(12) "Yet," he adds, "the Elementals are not spirits, because they have flesh, blood and bones; they live and propagate offspring; they cat and talk, act and sleep, &c., and consequently they cannot be properly called 'spirits.' They are beings occupying a place between men and spirits, resembling men and spirits, resembling men and women in their organization and form, and resembling spirits in the rapidity of their locomotion." (Philosophia Occulta, translated by Franz Hartmann.) Later the same author calls these creatures composita, inasmuch as the substance out of which they are composed seems to be a composite of spirit and matter. He uses color to explain the idea. Thus, the mixture of blue and red gives purple, a new color, resembling neither of the others yet composed of both. Such is the case with the Nature spirits; they resemble neither spiritual creatures nor material beings, yet are composed of the substance which we may call spiritual matter, or ether.

(11) Nor is it only by reason of knowledge acquired and intuitive that the soul of man holds the first rank among created things, but also by reason of power. Just as angels preside over the elements, so does the soul rule the members of the body. Those souls which attain a special degree of power not only rule their own body but those of others also. If they wish a sick man to recover he recovers, or a person in health to fall ill he becomes ill, or if they will the presence of a person he comes to them. According as the effects produced by these powerful souls are good or bad they are termed miracles or sorceries. These souls differ from common folk in three ways: (1) What others only see in dreams they see in their waking moments. (2) While others' wills only affect their own bodies, these, by will-power, can move bodies extraneous to themselves. (3) The knowledge which others acquire by laborious learning comes to them by intuition.

(12) Next above the Plane of Ethereal Substance comes the Plane of Energy (A), which comprises the ordinary forms of Energy known to science, its seven sub-planes being, respectively, Heat; Light; Magnetism; Electricity, and Attraction (including Gravitation, Cohesion, Chemical Affinity, etc.) and several other forms of energy indicated by scientific experiments but not as yet named or classified. The Plane of Energy (B) comprises seven subplanes of higher forms of energy not as yet discovered by science, but which have been called "Nature's Finer Forces" and which are called into operation in manifestations of certain forms of mental phenomena, and by which such phenomena becomes possible. The Plane of Energy (C) comprises seven sub-planes of energy so highly organized that it bears many of the characteristics of "life," but which is not recognized by the minds of men on the ordinary plane of development, being available for the use on beings of the Spiritual Plane alone--such energy is unthinkable to ordinary man, and may be considered almost as "the divine power." The beings employing the same are as "gods" compared even to the highest human types known to us.
