(41) In The Principles of Light and Color, Edwin D. Babbitt confirms the correspondence of the color and musical scales: "As C is at the bottom of the musical scale and made with the coarsest waves of air, so is red at the bottom of the chromatic scale and made with the coarsest waves of luminous ether. As the musical note B [the seventh note of the scale] requires 45 vibrations of air every time the note C at the lower end of the scale requires 24, or but little over half as many, so does extreme violet require about 300 trillions of vibrations of ether in a second, while extreme red requires only about 450 trillions, which also are but little more than half as many. When one musical octave is finished another one commences and progresses with just twice as many vibrations as were used in the first octave, and so the same notes are repeated on a finer scale. In the same way when the scale of colors visible to the ordinary eye is completed in the violet, another octave of finer invisible colors, with just twice as many vibrations, will commence and progress on precisely the same law."

(52) In addition to the colors of the spectrum there are a vast number of vibratory color waves, some too low and others too high to be registered by the human optical apparatus. It is appalling to contemplate man's colossal ignorance concerning these vistas of abstract space. As in the past man explored unknown continents, so in the future, armed with curious implements fashioned for the purpose, he will explore these little known fastnesses of light, color, sound, and consciousness.

(33) Since light is the basic physical manifestation of life, bathing all creation in its radiance, it is highly important to realize, in part at least, the subtle nature of this divine substance. That which is called light is actually a rate of vibration causing certain reactions upon the optic nerve. Few realize how they are walled in by the limitations

(7) Scientists have offered the illustration of a rapidly moving wheel, top, or cylinder, to show the effects of increasing rates of vibration. The illustration supposes a wheel, top, or revolving cylinder, running at a low rate of speed--we will call this revolving thing "the object" in following out the illustration. Let us suppose the object moving slowly. It may be seen readily, but no sound of its movement reaches the ear. The speed is gradually increased. In a few moments its movement becomes so rapid that a deep growl or low note may be heard. Then as the rate is increased the note rises one in the musical scale. Then, the motion being still further increased, the next highest note is distinguished. Then, one after another, all the notes of the musical scale appear, rising higher and higher as the motion is increased. Finally when the motions have reached a certain rate the final note perceptible to human ears is reached and the shrill, piercing shriek dies away, and silence follows. No sound is heard from the revolving object, the rate of motion being so high that the human ear cannot register the vibrations. Then comes the perception of rising degrees of Heat. Then after quite a time the eye catches a glimpse of the object becoming a dull dark reddish color. As the rate increases, the red becomes brighter. Then as the speed is increased, the red melts into an orange. Then the orange melts into a yellow. Then follow, successively, the shades of green, blue, indigo, and finally violet, as the rate of sped increases. Then the violet shades away, and all color disappears, the human eye not being able to register them. But there are invisible rays emanating from the revolving object, the rays that are used in photographing, and other subtle rays of light. Then begin to manifest the peculiar rays known as the "X Rays," etc., as the constitution of the object changes. Electricity and Magnetism are emitted when the appropriate rate of vibration is attained.

(6) On the accompanying circular chart, the concentric rings represent diagrammatically the forty rates of vibration (called by the Qabbalists Spheres) which emanate from AIN SOPH. The circle X 1 is the outer boundary of space. It circumscribes the area of AIN SOPH. The nature of AIN SOPH Itself is divided into three parts, represented by the spaces respectively between X 1 and X 2, X 2 and X 3, X 3 and A 1; thus:

(3) Modern Science has proven that all that we call Matter and Energy are but "modes of vibratory motion," and some of the more advanced scientists are rapidly moving toward the positions of the occultists who hold that the phenomena of Mind are likewise modes of vibration or motion. Let us see what science has to say regarding the question of vibrations in matter and energy.

(22) In this chart is set forth a summary of Fludd's theory of universal music. The interval between the element of earth and the highest heaven is considered as a double octave, thus showing the two extremes of existence to be in disdiapason harmony. It is signifies that the highest heaven, the sun, and the earth have the same time, the difference being in pitch. The sun is the lower octave of the highest heaven and the earth the lower octave of the sun. The lower octave (Γ to G) comprises that part of the universe in which substance predominate over energy. Its harmonies, therefore, are more gross than those of the higher octave (G to g) wherein energy predominates over substance. "If struck in the more spiritual part," writes Fludd, "the monochord will give eternal life; if in the more material part, transitory life." It will be noted that certain elements, planets, and celestial spheres sustain a harmonic ratio to each other, Fludd advanced this as a key to the sympathies and antipathies existing between the various departments of Nature.

(4) Light and Darkness are poles of the same thing, with many degrees between them. The musical scale is the same--starting with "C" you move upward until you reach another "C" and so on, the differences between the two ends of the board being the same, with many degrees between the two extremes. The scale of color is the same-higher and lower vibrations being the only difference between high violet and low red. Large and Small are relative. So are Noise and Quiet; Hard and Soft follow the rule. Likewise Sharp and Dull. Positive and Negative are two poles of the same thing, with countless degrees between them.

(2) O Rā, in that thy name of Rā, since thou passest through an Eye of seven cubits, whose pupil is of three: do thou then make me sound, I am a powerful Chu, let thy soundness be my soundness

(18) Some are strongest in the quality of the tone or sound, and those are light or bright also; and when the light shineth on them, they look like the rising of the flash of lightning, as if something would lift itself aloft there.

(28) So truly does advanced modern scientific thought recognize the nature of vibrations, that the axiom is announced that "The difference in things consists entirely of difference in vibrations." This axiom is akin to the ancient occult aphorism that "Things manifest differences according to their rate of vibrations." So, it is seen, all human investigation tends to prove the truth of the old occult axiom that "Everything vibrates." IV. The Principle of Rhythm The Principle of Rhythm manifests that universal regular swing or time-beat which is apparent in all the manifested world, from its highest to its lowest manifestation. The ancient occult axiom "Everything beats time" expresses this fundamental fact of the Cosmos.

(10) Every thought, emotion or mental state has its corresponding rate and mode of vibration. And by an effort of the will of the person, or of other persons, these mental states may be reproduced, just as a musical tone may be reproduced by causing an instrument to vibrate at a certain rate--just as color may be reproduced in the same may. By a knowledge of the Principle of Vibration, as applied to Mental Phenomena, one may polarize his mind at any degree he wishes, thus gaining a perfect control over his mental states, moods, etc. In the same way he may affect the minds of others, producing the desired mental states in them. In short, he may be able to produce on the Mental Plane that which science produces on the Physical Plane--namely, "Vibrations at Will." This power of course may be acquired only by the proper instruction, exercises, practice, etc., the science being that of Mental Transmutation, one of the branches of the Hermetic Art.

(35) of the sense perceptions. Not only is there a great deal more to light than anyone has ever seen but there are also unknown forms of light which no optical equipment will ever register. There are unnumbered colors which cannot be seen, as well as sounds which cannot be heard, odors which cannot be smelt, flavors which cannot be tasted, and substances which cannot be felt. Man is thus surrounded by a supersensible universe of which he knows nothing because the centers of sense perception within himself have not been developed sufficiently to respond to the subtler rates of vibration of which that universe is composed.

(3) 3. The Principle of Vibration "Nothing rests; everything moves; everything vibrates." --The Kybalion. This Principle embodies the truth that "everything is in motion"; "everything vibrates"; "nothing is at rest"; facts which Modern Science endorses, and which each new scientific discovery tends to verify. And yet this Hermetic Principle was enunciated thousands of years ago, by the Masters of Ancient Egypt. This Principle explains that the differences between different manifestations of Matter, Energy, Mind, and even Spirit, result largely from varying rates of Vibration. From THE ALL, which is Pure Spirit, down to the grossest form of Matter, all is in vibration--the higher the vibration, the higher the position in the scale. The vibration of Spirit is at such an infinite rate of intensity and rapidity that it is practically at rest--just as a rapidly moving wheel seems to be motionless. And at the other end of the scale, there are gross forms of matter whose vibrations are so low as to seem at rest. Between these poles, there are millions upon millions of varying degrees of vibration. From corpuscle and electron, atom and molecule, to worlds and universes, everything is in vibratory motion. This is also true on the planes of energy and force (which are but varying degrees of vibration); and also on the mental planes (whose states depend upon vibrations); and even on to the spiritual planes. An understanding of this Principle, with the appropriate formulas, enables Hermetic students to control their own mental vibrations as well as those of others. The Masters also apply this Principle to the conquering of Natural phenomena, in various ways. "He who understands the Principle of Vibration, has grasped the scepter of power," says one of the old writers.

(25) A writer has said: "Science offers the illustration of a rapidly moving wheel, top, or cylinder, to show the effects of increasing rates of vibration. The illustration supposes a wheel, top, or revolving cylinder, running at a high rate of speed—we will call this revolving thing 'the object' in following out the illustration. Let us suppose the object to be moving slowly. It may be seen readily, but no sound of its movement reaches the ear. Then the speed is gradually increased. In a few moments the movement becomes so rapid that a deep growl or low note may be heard. Then as the rate of motion is increased the note rises higher in the musical scale. Then, the motion being still further increased, the next highest note is distinguished. Then, one after another, all the notes of the musical scale appear, rising higher and higher as the motion is increased.

(11) The esoteric teachings, as has been said, clearly and positively state that before there began the wonderful process of Evolution from simple to more complex forms of manifestation—from lower to higher—there must first have been an "involution" or in-folding of the World Soul into the simple, gross, elemental forms of matter. The vibrations must have been first lowered, before they can have been increased.

(11) A little reflection on what we have said will show the student that the Principle of Vibration underlies the wonderful phenomena of the power manifested by the Masters and Adepts, who are able to apparently set aside the Laws of Nature, but who, in reality, are simply using one law against another; one principle against others; and who accomplish their results by changing the vibrations of material objects, or forms of energy, and thus perform what are commonly called "miracles."

(40) There are numerous arbitrary arrangements setting forth the mutual relationships of the planets, the colors, and the musical notes. The most satisfactory system is that based upon the law of the octave. The sense of hearing has a much wider scope than that of sight, for whereas the ear can register from nine to eleven octaves of sound the eye is restricted to the cognition of but seven fundamental color tones, or one tone short of the octave. Red, when posited as the lowest color tone in the scale of chromatics, thus corresponds to do, the first note of the musical scale. Continuing the analogy, orange corresponds to re, yellow to mi, green to fa, blue to sol, indigo to la, and violet to si (ti). The eighth color tone necessary to complete the scale should be the higher octave of red, the first color tone. The accuracy of the above arrangement is attested by two striking facts: (1) the three fundamental notes of the musical scale--the first, the third, and the fifth--correspond with the three primary colors--red, yellow, and blue; (2) the seventh, and least perfect, note of the musical scale corresponds with purple, the least perfect tone of the color scale.

(1) One of the most interesting points of the Rosicrucian teachings to the average student is that which is concerned with the Aura, or Psychic Atmosphere of the Human Individual, and the Astral Colors which manifest in that Aura, and otherwise.

(7) Passing over several unimportant auric elements of a lower degree, the student is asked to consider the most interesting phenomena of the "auric colors" which represent the mental and emotional elements in the soul of the man or woman. These elements are the characteristic features of the aura when perceived by clairvoyant vision. The aura, seen in this way, presents the appearance of a luminous cloud composed of varied and shifting colors, extending in egg-shape to a distance of about two or three feet from the body, and gradually growing fainter toward its outward limits until it finally disappears.
