(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.

(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.

(18) In addition to the ordinary colors named above, there are several shades which cannot be named, for they correspond to colors outside of the field of human vision, such as "infra red" and "ultra violet." Without going deeply into this phase of the subject, it may be said that the "ultra violet" auric colors denote high spiritual powers manifested in the direction of the highest and most worthy aims and ends; while the "infra red" auric colors denote psychic powers employed in unworthy ways and for base ends—as for instance, that which the occultists know as "black magic." There are two other auric colors which are impossible to describe in words, for there are no terms adequate for such expression. These colors are as follows: (1) the true primary yellow, which indicates the highest spiritual illumination of the intellect; and (2) true pure white, or a peculiar brilliancy and transparency, which indicates the presence of the awakened spirit.

(22) Black is really an absence of color, while White is really a harmonious blending of all colors. The blending of the Primary Colors in varied proportions produce what are known as the "hues" of color; and adding White we obtain "tints," while mixing Black produces "shades." Key to the Auric Colors An understanding of the basic character of the Three Primary Auric Colors, and of Auric Black and Auric White, gives the student the key to the whole range of auric coloring. For this purpose the following table is presented: The Red Group . Red represents the physical nature, and its presence always indicates the existence and activity of that part of the nature of man.

(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.

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

(67) Timaeus: Concerning colors, then, the following explanation will be the most probable and worthy of a judicious account. Of the particles which fly off from the rest and strike into the visual stream some are smaller, some larger, and some equal to the particles of the stream itself; those, then, that are equal are imperceptible, and we term them “transparent”; while the larger and smaller particles—of which the one kind contracts, the other dilates the visual stream—are akin to the particles of heat and cold which affect the flesh,

(1) Seen from a distance, objects appear reduced and close together, however far apart they be: within easy range, their sizes and the distances that separate them are observed correctly.

Distant objects show in this reduction because they must be drawn together for vision and the light must be concentrated to suit the size of the pupil; besides, as we are placed farther and farther away from the material mass under observation, it is more and more the bare form that reaches us, stripped, so to speak, of magnitude as of all other quality.

Or it may be that we appreciate the magnitude of an object by observing the salience and recession of its several parts, so that to perceive its true size we must have it close at hand.

Or again, it may be that magnitude is known incidentally from the observation of colour. With an object at hand we know how much space is covered by the colour; at a distance, only that something is coloured, for the parts, quantitatively distinct among themselves, do not give us the precise knowledge of that quantity, the colours themselves reaching us only in a blurred impression.

What wonder, then, if size be like sound- reduced when the form reaches us but faintly- for in sound the hearing is concerned only about the form; magnitude is not discerned except incidentally.

Well, in hearing magnitude is known incidentally; but how? Touch conveys a direct impression of a visible object; what gives us the same direct impression of an object of hearing?

The magnitude of a sound is known not by actual quantity but by degree of impact, by intensity- and this in no indirect knowledge; the ear appreciates a certain degree of force, exactly as the palate perceives by no indirect knowledge, a certain degree of sweetness. But the true magnitude of a sound is its extension; this the hearing may define to itself incidentally by deduction from the degree of intensity but not to the point of precision. The intensity is merely the definite effect at a particular spot; the magnitude is a matter of totality, the sum of space occupied.

Still the colours seen from a distance are faint; but they are not small as the masses are.

True; but there is the common fact of diminution. There is colour with its diminution, faintness; there is magnitude with its diminution, smallness; and magnitude follows colour diminishing stage by stage with it.

But, the phenomenon is more easily explained by the example of things of wide variety. Take mountains dotted with houses, woods and other land-marks; the observation of each detail gives us the means of calculating, by the single objects noted, the total extent covered: but, where no such detail of form reaches us, our vision, which deals with detail, has not the means towards the knowledge of the whole by measurement of any one clearly discerned magnitude. This applies even to objects of vision close at hand: where there is variety and the eye sweeps over all at one glance so that the forms are not all caught, the total appears the less in proportion to the detail which has escaped the eye; observe each single point and then you can estimate the volume precisely. Again, magnitudes of one colour and unbroken form trick the sense of quantity: the vision can no longer estimate by the particular; it slips away, not finding the stand-by of the difference between part and part.

It was the detail that prevented a near object deceiving our sense of magnitude: in the case of the distant object, because the eye does not pass stage by stage through the stretch of intervening space so as to note its forms, therefore it cannot report the magnitude of that space.

(29) It is also a part of the teachings that the Three Primary Colors have a decided therapeutic effect, and that one may apply the principle in healing work. The colors may be applied either by means of physical colors placed in the environment of the person, or else held in the mind of the mental healer giving the treatment. Here is the Therapeutic Scale of Colors: Therapeutic Scale of Colors Blues, Violet, Lavender, etc. , have a cooling and soothing effect upon the nervous system, and upon the blood and bodily organs.
