The Universal Ether, which is postulated by science without its nature being understood clearly, is held by the Hermetists to be but a higher manifestation of that which is erroneously called matter--that is to say, Matter at a higher degree of vibration--and is called by them "The Ethereal Substance." The Hermetists teach that this Ethereal Substance is of extreme tenuity and elasticity, and pervades universal space, serving as a medium of transmission of waves of vibratory energy, such as heat, light, electricity, magnetism, etc.
The Teachings are that The Ethereal Substance is a connecting link between the forms of vibratory energy known as "Matter" on the one hand, and "Energy or Force" on the other; and also that it manifests a degree of vibration, in rate and mode, entirely its own.
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.
When the object reaches a certain rate of vibration its molecules disintegrate, and resolve themselves into the original elements or atoms.
Then the atoms, following the Principle of Vibration, are separated into the countless corpuscles of which they are composed.
And finally, even the corpuscles disappear and the object may be said to Be composed of The Ethereal Substance.
Science does not dare to follow the illustration further, but the Hermetists teach that if the vibrations be continually increased the object would mount up the successive states of manifestation and would in turn manifest the various mental stages, and then on Spiritward, until it would finally re-enter THE ALL, which is Absolute Spirit.
The "object," however, would have ceased to be an "object" long before the stage of Ethereal Substance was reached, but otherwise the illustration is correct inasmuch as it shows the effect of constantly increased rates and modes of vibration.
The universal fluid or medium of occult philosophy — Lévi's Great Magical Agent — that transmits will, thought, and magical influence between minds and matter, and preserves the impress of all forms and actions as a book of consciences; cognate with akasha and the anima mundi. Distinct from cosmic_sympathy (a doctrine of hidden affinity) in being a substantival medium that can be charged, directed, and abused.
The 'Ethereal Substance' described serves as a universal medium pervading space and transmitting vibratory energy, closely aligning with the definition of astral light or akasha.
The Hermetic axiom that the structure of the cosmos is reflected at every scale — 'as above, so below; as within, so without' — making each level a legible map of the others.
The illustration of the wheel implies a correspondence between physical motion rates and metaphysical states (sound, light, spirit).
A chain of divine beings or principles flowing downward from a single transcendent source (the One or the Father), each level less perfect than the one above.
The passage outlines a hierarchy of manifestation from Matter to Ethereal Substance to Mental Stages to Spirit to THE ALL based on vibratory rates.
The Hermetic doctrine that THE ALL is Mind, and the Universe is mental in nature — a created thought held in the mind of THE ALL. Distinct from unity_of_being in specifying WHAT the underlying oneness is (mind, not an unspecified single substance), and from logos (a mediating ordering word BETWEEN a transcendent God and a separate material world) in collapsing that mediation entirely — under mentalism there is no world outside mind to mediate to.
The text states that as vibration increases, the object manifests 'various mental stages' before reaching Spirit, implying the universe is fundamentally mental in its higher states.
The soul's journey back to its divine origin, reversing the fall into matter through stages of purification or illumination.
The passage describes the theoretical progression of an object increasing in vibration until it re-enters THE ALL, illustrating a path back to the Absolute Spirit.
The doctrine that all existence is ultimately one substance or one divine reality; non-duality as a theological claim.
The text describes a single continuum where matter, energy, and spirit are manifestations of the same underlying substance (Ethereal Substance/THE ALL) differing only in vibration.
The Hermetic doctrine that nothing rests — matter, energy, mind, and spirit are a single continuum differing only in rate of vibration, from the grossest matter to the least material spirit. Distinct from cosmic_sympathy (affinity resonating BETWEEN separate things) in being a claim about what constitutes any one thing in the first place, and from magical_equilibrium (Lévi's operational balancing technique, which presupposes some vibration doctrine rather than stating this general principle).
The passage is explicitly dedicated to explaining the Hermetic Principle of Vibration, detailing how matter, energy, and spirit differ only in rate of vibration.
