The positive and negative interchange of this true sympathetic stream keeps intact the magnetic force of the polar envelope of the earth; making it, as it were, a great magnet of itself. The fact of this magnetic force being universally present, on and in our planet, proves the immeasurable speed and power of etheric sympathetic interchange. Thus it is that, from the velocity of these sympathetic rays, the earth's standard of heat and light is evolved and kept in balance. This interchange of sympathetic radiation, between the solar world and its system of planets, equates the sympathetic volume by the reception of the full amount expended on sympathetic distribution; thus showing the never-ending restoration of equilibrium by the same medium that disturbs it during intermittent sympathetic action. There are very many facts in vibratory physics which prove that the volume of heat, supposed by many to emanate from the sun, if concentrated upon a centre of the volume represented by the sun, would give enough focal force, if projected upon the system of planets that is under its control, to vaporize them in one month's time. A ray of heat one billion times greater than the whole volume of the sun represents could not pass through the dark vacuous boundaries which lie between us and the sun without being neutralized and absorbed. What is Electricity? Electricity is the result of three differentiated sympathetic flows, combining the celestial and terrestrial flows by an order of assimilation negatively attractive in its character. It is one of Nature's efforts to restore attractive differentiation. In analyzing this triple union in its vibratory philosophy, I find the highest order of perfection in this assimilative action of Nature. The whole condition is atomic, and is the introductory one which has an affinity for terrestrial centres, uniting magnetically with the Polar stream; in other words, uniting with the Polar stream by neutral affinity. The magnetic or electric forces of the earth are thus kept in stable equilibrium by this triune force, and the chords of this force may be expressed as 1st, the dominant, 2nd, the harmonic, and 3rd, the enharmonic. The value of each is, one to the other, in the rates of figures, true thirds. E flat--transmissive chord or dominant; A flat--harmonic; A double flat--enharmonic. The unition of the two prime thirds is so rapid, when the negative and the positive conditions reach a certain range of vibratory motion, as to be compared to an explosion. During this action the positive electric stream is liberated and immediately seeks its neutral terrestrial centre, or centre of highest attraction.
