(30) In constructing their temples of initiation, the early priests frequently demonstrated their superior knowledge of the principles underlying the phenomena known as vibration. A considerable part of the Mystery rituals consisted of invocations and intonements, for which purpose special sound chambers were constructed. A word whispered in one of these apartments was so intensified that the reverberations made the entire building sway and be filled with a deafening roar. The very wood and stone used in the erection of these sacred buildings eventually became so thoroughly permeated with the sound vibrations of the religious ceremonies that when struck they would reproduce the same tones thus repeatedly impressed into their substances by the rituals.

(36) By that sound all powers are moved in heaven, so that all things grow joyfully, and generate very beautifully: And as the divine power is manifold and various, so also the sound or Mercurius is manifold and various.

(67) Now what is it that makes the Hearing, that you can hear that which stirs and makes a Noise? Wilt thou say that it is caused by the Noise of that outward Thing which gives the Sound? No! there must also be somewhat that must receive the Sound, and qualify or mix with the Sound, and distinguish the Sound of what is played or sung; the outward cannot do that alone, the inward must receive and distinguish the Noise. Behold, here you find the Beginning of the Life, and the Tincture wherein the Life consists; for the Tincture of the Crack in the Springing up of the Life, in the Breaking-open of the dark Gate, stands in the Sounding, and has its Gate open (next the Fire-flash near the Eyes) and receives the Noise of whatsoever sounds.

(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."

(5) But some doubt arises when we consider the phenomena of hearing.

Perhaps we are to understand the process thus: the air is modified by the first movement; layer by layer it is successively acted upon by the object causing the sound: it finally impinges in that modified form upon the sense, the entire progression being governed by the fact that all the air from starting point to hearing point is similarly affected.

Perhaps, on the other hand, the intervenient is modified only by the accident of its midway position, so that, failing any intervenient, whatsoever sound two bodies in clash might make would impinge without medium upon our sense?

Still air is necessary; there could be no sound in the absence of the air set vibrating in the first movement, however different be the case with the intervenient from that onwards to the perception point.

The air would thus appear to be the dominant in the production of sound: two bodies would clash without even an incipient sound, but that the air, struck in their rapid meeting and hurled outward, passes on the movement successively till it reaches the ears and the sense of hearing.

But if the determinant is the air, and the impression is simply of air-movements, what accounts for the differences among voices and other sounds? The sound of bronze against bronze is different from that of bronze against some other substance: and so on; the air and its vibration remain the one thing, yet the difference in sounds is much more than a matter of greater or less intensity.

If we decide that sound is caused by a percussion upon the air, then obviously nothing turning upon the distinctive nature of air is in question: it sounds at a moment in which it is simply a solid body, until it is sent pulsing outwards: thus air in itself is not essential to the production of sound; all is done by clashing solids as they meet and that percussion, reaching the sense, is the sound. This is shown also by the sounds formed within living beings not in air but by the friction of parts; for example, the grinding of teeth and the crunching of bones against each other in the bending of the body, cases in which the air does not intervene.

But all this may now be left over; we are brought to the same conclusion as in the case of sight; the phenomena of hearing arise similarly in a certain co-sensitiveness inherent in a living whole.

(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

(12) As one of the old Hermetic writers has truly said: "He who understands the Principle of Vibration, has grasped the scepter of Power."

(4) O Rā, in that thy name of Rā, since thou openest the secrets of the Ammehit, which gladdeneth the hearts of the Divine Circle: do thou then give me my heart. I am a powerful Chu, let thy soundness be my soundness, and the soundness of thy limbs be the soundness of my limbs

(62) Then afterwards, that the sound is in every power, and the tone or tune of the sound is according to the quality of every power; and therein consisteth the total heavenly kingdom of joy. From this divine Salitter and Mercurius all angels are made, viz. out of the body of nature. Question.

(4) O thou who guidest the Bark of Rā, sound is thy rigging and free from disaster as thou passest on to the Tank of Flame

(35) The second form or property of heaven in the divine pomp or state is Mercurius or the sound, as in the Salitter of the earth there is the sound, whence there grows gold, silver, copper, iron and the like; of which men make all manner of musical instruments for sounding or for mirth, as bells, organpipes and other things that make a sound: There is likewise a sound in all the creatures upon earth, else all would be in stillness and silence.

(30) Then the tone riseth up; and the hard spirit beateth, striketh or thumpeth; but the sweet makes that beating or striking mild; and the bitter divideth it according to the condition or kind of every quality; the fourth causes the ringing; the fifth causes joyfulness; and the compacted incorporated sounding is the tone or tune, or the sixth spirit.

(47) And when one power toucheth or stirreth the other, and tuneth or soundeth, then the tune or sound goeth forth, and riseth up again in all the powers of the Father; and so all the powers of the Father are again affected therewith, whereby they are always impregnated with the tune, and continually generate it again in every power:

(24) And now when it seeth and heareth the divine tone, tune and sound rise up, which is externally without it, then is its spirit affected and kindled with joy, and elevateth itself in its princely seat, and singeth and ringeth forth very joyful words concerning God's holiness, and concerning the fruit and vegetation of the eternal life.

(10) Hardness is the fountain or wellspring of the tone, but it alone cannot generate the same, yet it is the father thereof, and the whole Salitter is the mother; otherwise, if the hardness were both father and mother of the tone, then a hard stone also must have a ringing sound. But a hard stone does make only a noise, like a knocking, as a seed or beginning of a tone, and that it is, certainly.

(2) But thou wilt ask, What is the tone or sound? Or how taketh this spirit its source and original? Answer.

(1) What you afterwards say is as follows: “ That some of those who suffer a mental alienation, energize enthusiastically on hearing cymbals or drums, or a certain modulated sound, such as those who are Corybantically inspired, those who are possessed by Sabazius, and those who are inspired by the mother of the Gods .” It is necessary, therefore, to discuss the causes of these things, and to show how they are definitely produced. That music, therefore, is of a motive nature, and is adapted to excite the affections, and that the melody of pipes produces or heals the disordered passions of the soul, changes the temperaments or dispositions of the body, and by some melodies causes a Bacchic fury, but by others occasions this fury to cease; and, likewise, how the differences of these accord with the several dispositions of the soul, and that an unstable and variable melody is adapted to ecstasies, such as are the melodies of Olympus, and others of the like kind; all these appear to me to be adduced in a way foreign to enthusiasm. For they are physical and human, and the work of our art; but nothing whatever of a divine nature in them presents itself to the view.

(53) And I asked the angel of peace who went with me: 'For whom are they preparing these instruments?'

(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.

(70) Thus now the Habitation of Man's Sound, wherein the Understanding is, must be from Eternity, although indeed in the Fall of Adam, Man has set himself in the Corruptibility, and in great Want of Understanding, as shall follow here. In like Manner also we find concerning the Smelling; for if the Spirit did not stand in the Sound, then no Smell of any Thing would press [or pierce] into the Essences; for the Spirit would be whole and swelled. But it standing thus in the Gate of the broken Darkness in the Crack and in the Sound, therefore all Virtues of all Things press in into that Gate, and try themselves by one another, and what the Essences of the Spirit love, that it desires, and draws the same into the Tincture; and then Hands and Mouth fall to it, and stuff it into the Stomach, into the outward Court of the four Elements, from whence the earthly Essences of the Stars and Elements feed. 7 1. And the Taste also is a Trying, and Attracting of the Tincture in the Essences of the Spirit. And so the Feeling also, if the Spirit of Man with its Essences did not stand in the Sound, there would be no Feeling; for when the sour Essences draw to them, then they awaken the bitter Prickle [or Sting] in the Fire-flash, which stirs itself, either by Griping, Thrusting, or Striking, and thereupon in all driving the bitter Prickle in the Fire-flash is awakened; and therein stands the Moving; [and] all in the Tincture.
