(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) Another low element in the human aura is that which may be called the auric element of "vital energy." This element is perceived by clairvoyants as having a very faint pinkish glow, sometimes filled with tiny sparks of vital magnetism if the person be very magnetic. It is occasionally visible to persons lacking clairvoyant vision, and appears to them in the form of vibrating air, similar to the heated air arising from a field on a very warm day, or from a heated stove.

(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

(26) 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 then heard from the revolving object, for its rate of motion is so high that the human ear cannot register the vibrations. Then comes the perception of rising degrees of Heat. After quite a time in which degrees of heat are being manifested without any sign of distinguishable color (though certain colors are there, but imperceptible to human vision) there gradually is manifested a dull dark reddish color in the revolving object. As the rate of speed increases, the red becomes brighter. Then, as the speed is still further increased, the red changes into an orange color. Then follow, successively, the shades of green, blue, indigo, and finally violet, as the rate of vibrations increase. Then the violet fades 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 be manifested 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.

(27) The various combinations of the three Primary Annie Colors are formed in connection with White and Black, as well as by the blending of the three themselves. These combinations of course result from the shades of mental and emotional activity manifested by the individual. But not only is the blending caused by the mixing of the colors themselves, in connection with Black and White, but in certain cases the body of one color is found to be streaked, striped, dotted, or clouded by other colors. At times there is perceived the mixture of two antagonistic color streams fighting against each other before blending. Again we see the effect of one color neutralizing another. In some cases great black clouds obscure the bright colors beneath, and then darken the fierce glow of color, just as is often witnessed in the case of a physical conflagration. Again, we find great flashes of bright yellow, or red, flaring across the field of the aura, showing agitation or the conflict of intellect and passion.

(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.

(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.

(67) Timaeus: and that large motion produces “loud” sound, and motion of the opposite kind “soft” sound. The subject of concords of sounds must necessarily be treated in a later part of our exposition. We have still remaining a fourth kind of sensation, which we must divide up seeing that it embraces numerous varieties, which, as a whole, we call “colors.” This consists of a flame which issues from the several bodies, and possesses particles so proportioned to the visual stream as to produce sensation; and as regards the visual stream, we have already stated merely the causes which produced it.

(4) In a similar manner, likewise, we must determine concerning the light of these powers. For the images of the Gods, indeed, are replete with a fulgid light. Those of archangels are full of supernatural light. Those of angels are luminous; but dæmons present themselves to the view with a turbid fire. The light of heroes is mingled with many things. And, with respect to archons, the light of those that have the government of the world is more pure; but of those that preside over matter, exhibits itself mingled from things of a dissimilar and contrary nature. And the light of souls manifests itself to be partibly filled with many of the mixtures which exist in generation.

(60) And the thunders according to the places where they fall, and all the divisions that are made among the lightnings that it may lighten, and their host that they may at once obey.

(4) 'The red colour of the lightning is the colour of fire, the white of water, the black of earth. Thus vanishes what we call the lightning, as a mere variety, being a name, arising from speech. What is true are the three colours.

(68) Timaeus: and dissolving the very passages of the eyes causes a volume of fire and water to pour from them, which we call “tears.” And this moving body, being itself fire, meets fire from the opposite direction; and as the one firestream is leaping out like a flash, and the other passing in and being quenched in the moisture, in the resultant mixture colors of all kinds are produced. This sensation we term “dazzling” and the object which causes it “bright” or “brilliant.” Again, when the kind of fire

(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.

(20) The habitual colors shown indicate the 'general character' of the person; the passing colors show what feeling, emotion, or passion (if any) is dominating him at that particular time." Another writer, describing the appearance of the aura of a person, has said: "The shades and colors of the aura present an ever-changing kaleidoscopic spectacle. The trained occultist is able to read the character of any person, as well as the nature of his passing thoughts and feelings, by simply studying the shifting colors of his aura.. To the developed occultist the mind and character becomes as an open book, to be studied carefully and intelligently. Even the student of occultism who has not been able to develop the clairvoyant vision to such a high degree, is soon able to develop the sense of psychic perception whereby he is able to at least 'feel' the vibrations of the aura, though he may not see the colors, and thus be able to interpret the mental states which have caused them. The principle of course is the same, as the colors are but the outward appearance of the vibrations themselves, just as the ordinary colors on the physical plane are merely the outward manifestations of vibrations of matter. But it must not be supposed that the human aura is always perceived in the appearance of a luminous cloud of ever-changing color. When we say that such is its characteristic appearance, we mean it in the same sense that we describe the ocean as a calm, deep body of greenish waters. We know, however, that at times the ocean presents no such appearance, but, instead, is seen as rising in great mountainous waves, white-capped, and threatening the tiny vessels of men with its power. Or again, we may define the word 'flame' in the sense of a steady, bright stream of burning gas, whereas, we know only too well that the word also indicates the great hot tongues of fiery force that stream out from the windows of a burning building and lick to destruction all with which it comes in contact. So it is with the human aura. At times it may be seen as a beautiful, calm, luminous atmosphere, presenting the appearance of a great opal under the rays of the sun. Again, it blazes like the flames of a great furnace, shooting forth great tongues of fire in this direction and that, rising and falling in great waves of emotional excitement, or passion, or perhaps whirling like a great fiery maelstrom toward its centre, or swirling in an outward movement away from its centre. Again, it may be seen as projecting from its depths smaller bodies or centres of mental vibration, which like sparks from a furnace detach themselves from the parent flame and travel far away in other directions—these are the projected thought forms of which all occultists are fond of speaking and which make plain many strange psychic occurrences." The Three Primary Auric Colors Like their physical counterparts, the Auric Colors are derived from three Primary Colors, from which. all the various combinations and colors are formed. These three primary colors, together with White and Black, give us the key to the entire auric spectrum.

(129) And of the Solar Circles, and of the Lunar, clashings, and of the Aërial Recesses; the Melody of Ether, and of the Sun, and of the phases of the Moon, and of the Air.

(1) Moreover, with respect to the tenuity and subtilty of light, the Gods extend a light so subtle that corporeal eyes cannot sustain it, but are affected in the same manner as fishes, when they are drawn upward from turbid and thick water into attenuated and diaphanous air. For men who survey divine fire are not able to breathe, through the subtilty of it, but become languid as soon as they perceive it, and are deprived of the use of their connascent spirit. Archangels, also, emit a light which is intolerable to respiration, yet their splendour is not equally pure with that of the Gods, nor similarly overpowering. The presence of angels renders the temperature of the air tolerable, so that theurgists are capable of being united to it. But when dæmons are present, the whole air is not at all affected; nor does the air, which surrounds them, become more attenuated; nor does a light precede them, in which, being previously received and preoccupied by the air, they unfold the form of themselves; nor are they surrounded by a certain splendour, which diffuses its light everywhere. When heroes appear, certain parts of the earth are moved, and sounds are heard around them; but, in short, the air does not become more attenuated, nor incommensurate to theurgists, so as to render them unable to receive it. But when archons are present, an assemblage of many luminous appearances runs round them, difficult to be borne, whether these appearances are mundane or terrestrial. They have not, however, a supermundane tenuity, nor even that of the supreme elements. And to the psychical appearances the air is more allied, and, being suspended from them, receives in itself their circumscription.

(5) The eternal Mind is in the great unsearchable Depth, and from Eternity is the indissoluble Band, and the Spirit in the and therein in the Center of the Deep is the reconceived Will to the Light; and the Will is the Desiring, and the Desiring attracts to it, and that which is attracted makes the Darkness in the Will, so that in the first Will, the second Will generates itself again, that it might fly out of the Darkness; and the second Will is the Mind, which discovers itself in the Darkness, and the [Discovery or] Glance breaks [or dispels] the Darkness, so that it stands in the Sound and in the Crack; where then the Flash sharpens itself, and so stands eternally in the broken Darkness, so that the Darkness thus stands in the Sound of the Stars. And in the Breaking of the Darkness, the reconceived Will is free, and dwells without the Darkness, in itself; and the Flash which there is the Separation and the Sharpness, and the Noise [or Sound] is the Dwelling of the Will, or of the continually conceived Mind; and the Noise and the Sharpness of the Flash are in the Dwelling of the Will free from the Darkness. And the Flash elevates the Will, and the Will triumphs in the Sharpness of the Flash, and the Will discovers itself in the Sharpness of the Sound in the Flash of the Light, without the Darkness in the Breaking, in the Infinity. And in that Infinity of the Flash, there is in every Discovery of the Whole fin the Particular (in every Reflection) again a Center of such a Birth as is in the Whole. And those Particulars are the Senses, and the Whole is the Mind out of which the Senses proceed; and therefore the Senses are mutable [or transitory,] and not in the Substance; but the Mind is whole, and in the Substance.

(3) From the midst of that radiance, the natural sound of Reality, reverberating like a thousand thunders simultaneously sounding, will come. That is the natural sound of thine own real self. Be not daunted thereby, nor terrified, nor awed.
