No wonder the invisible beings have rebelled. They will follow a Master, but they resent the interference of a fool. It is not the fools they fear, however. The men they fear are the great scientists. Man’s progress in science has been such that he _must_ purify his motives, or he will be destroyed. That is one reason why I am preaching brotherhood, in an attempt to save men from their own folly. Once let the feeling for brotherhood become general, and these experiments with unknown forces would be less dangerous. Mankind as a mass might work with the power of a White Master, whose motives are always unselfish. The great scientists come nearer than anybody else to that pure working with mind for mind’s own sake, which I recently described in writing of a great being, a great Initiator, who serves the world by influencing _along the line of evolutionary law_ the thoughts of certain men who are the chosen instruments of evolution. How little men know of the unseen world surrounding them! I recently followed you into a lecture room in New York that was even more crowded with invisible beings than with men and women. Your restlessness there had cause, as you well knew. The purpose of that meeting was to form a nucleus of a society of curiosity-seekers for investigating the unseen, for necromancy and ceremonial magic. Madness of madness! I heard one man express the determination that the proposed society should not, like the Society for Psychical Research, close its doors to the outside world; but that the society should invite _all_ who were interested in the investigation of the unseen, including the newspaper reporters. A press agent for the occult! Let me describe a few of the auditors who were invisible to any in the room except one person: A long lean hungry being with the face of a gargoyle and the stomach of an unfed leech yearned over the gathering. He was almost affectionate in his interest in one of the speakers. Another, bloated and lethargic, had already fed himself since entering the room. Another, frightened and tortured, was seeking an exit; but could not get outside the desire-aura of one of the participants in that orgy of curiosity. Another, powerful and malignant, moved from place to place, selecting his future victims. _He_ will be present at the meetings of the society. He will try to keep it alive, for he knows of a fascinating possibility which I shall not record here. Why do you go to such places? _April 18._ LETTER XXVIII THE GLORY OF WAR I HAVE written of the beauty of peace; but I now want to write of the glory of war, for war has its glories. Anything that arouses man to the highest pitch of enthusiasm is glorious; for what is glory but a radiation of light, a burst of that life which is the Sun in man?
