Many observations also have led to the conclusion that when the lines are kept straight by the force of the pulsating waves from a healthy and vigorous body, "it seems to be almost entirely protected from the attack of evil physical influences, such as germs of disease--such germs being repelled and carried away by the outrush of the life-force: but when from any cause--through weakness, through wound or injury, through over-fatigue, through extreme depression of spirits, or through the excesses of an irregular life--an unusually large amount of vitality is required to repair damage or waste, within the body, and there is consequently a serious diminution in the quantity radiated, this system of defense becomes dangerously weak, and it is comparatively easy for the deadly germs to effect an entrance." The third aura is that which expresses one's desires--a kind of mirror in which every feeling, every desire, every thought almost, of the personality is reflected. This changes constantly, in some people, accordingly as they are swayed by their impulses. Its colors, brilliancy, rate of pulsations, alter from moment to moment, or minute to minute. "An outburst of anger will charge the whole aura with deep-red flashes on a black ground; a sudden fright in a moment will change everything to a mass of ghastly livid gray." Connected with this, and yet, seemingly, of a separate character, are the radiations of the aura that express the progress of the personality into higher and better appreciation of the things of mind and spirit. The more intellectual and spiritual one becomes the more steady and beautiful are the colors and radiations of this aura, and the variations and distressing manifestations of the evil desires of the third aura become less apparent and distinct. The fifth aura is the highest at present discernible. It manifests the spiritual development of the individual and is of almost inconceivable delicacy and beauty. It seems to be a cloud of living light--the word cloud being used for want of a better term. In the concrete examples of aura that were presented at the Exposition, that which radiated from a wise mother showing her protective love for her infant, was in the form of outspread wings of a beautiful rosy tint, the wings held together at the articulations by a sheaf-like mass of golden yellow. Selfish ambition, sudden fear, explosive anger, selfishness, grasping animal affection, greed, jealousy, jealousy mixed with anger, gloom, murderous hatred, were all displayed in peculiar, hideous, and repulsive forms and colors. Pure, radiating affection, on the other hand, was represented in the form and color of a round body exhaling rays as from a rosy sun. Strange to say, though I had never read anything explicit upon this subject before, I had always conceived of pure affection as giving forth radiations of this exact appearance.
