The brain is not a laboratory. It is as static as the head of the positive negative attractor, [21] until influenced by certain orders of vibration, when it reveals the true character of the outreach so induced. The brain is the high resonating receptacle where the sympathetic celestial acts, and where molecular and atomic motion exhibits itself, as according to the intensification brought to bear upon it by the celestial mind flow. The cerebral forces, in their control of the physical organism, reveal to us the infinite power of the finer or spiritual fluid, though not immaterial, over the crude molecular. The luminous, etheric, protoplastic element, which is the highest tenuous condition of the ether, fills the regions of infinite space, and in its radiating outreach gives birth to the prime neutral centres that carry the planetary worlds through their ranges of motion. If the minds of all the most learned sages, of all time, were concentrated, into one mind, that one would be too feeble, in its mental outreach, to comprehend the conditions associated with the fourth order of sympathetic condensation. The controversies of the past in regard to the condensation of invisible matter prove this. The chemistry of the infinite and the chemistry of the finite are as wide apart, in their sympathetic ranges, as is the velocity of light from the movement of the hour-hand of a clock. Even the analysis of the visible conditions taxes our highest powers of concentration. The question naturally arises, Why is this condition of ether always under a state of luminosity of an especial order? Its characteristics are such, from its infinite tenuity and the sympathetic activity with which it is impregnated, that it possesses an order of vibratory, oscillatory velocity, which causes it to evolve its own luminosity. This celestial, latent power, that induces luminosity in this medium, is the same that registers in all aggregated forms of matter, visible and invisible. It is held in corpuscular embrace until liberated by a compound vibratory negative medium.
