I have been writing about a conversation I had with a +great and troubled soul.” + +“Yes, I know.” + +“You know, do you? Were you listening?” + +“Through my long-distance telephone.” + +“Brilliant invention, the telephone,” I observed. “Did you inspire the +invention?” + +“I? Oh, no! I worked against it.” + +“And why?” + +“It is not well that man should know too much.” + +“But when man makes discoveries, notwithstanding your efforts to hinder +him, you attempt to use those discoveries against him, do you not?” + +“Of course.” + +“You interest me,” I said. “And were you interested by my conversation +with the soul of Friedrich Nietzsche?” + +“More interested than you can imagine, until I tell you why.” + +“And you will tell me why?” + +“There is no reason for my not telling you. I am frank with those who +see through me.” + +“Why don’t you teach that to the Germans?” + +“Because it would spoil my game. I want to destroy them after I have +used them, and if they should turn frank, they would be so thorough in +their frankness that they would disarm the indignant world.” + +“They are frank enough in their brutality,” I said. + +“Oh, yes! But that is another matter. Should they be frank in their +repentance, the world would forgive them.” + +“But what of Nietzsche?” I questioned. + +“Only this, that it was I who inspired him.” + +“You did your work thoroughly.” + +“I do my work as thoroughly as it can be done.” + +“Tell me more,” I urged. + +“What a worker was lost in you,” he exclaimed, “when you chose good for +your standard!” + +“But I am an excellent worker,” I insisted. “I have even balked some of +your work.” + +He laughed, a quick, sharp laugh. + +“Don’t think that I care too much for that,” he said. “There is more +than one road for me. If you block the door, I can go in by the window.” + +“And how did you go in to Nietzsche?” + +“Sometimes by one way, sometimes by another. He only locked his door +against man, and you see I also am Beyond Man.” + +“I perceived that at our first meeting. He who goes beyond man must +make the choice between good and evil.” + +“There is no fooling you,” he said, “and so I no longer try. Yes, it +was I who inspired Nietzsche to preach Beyond Man to the Germans, who +could only choose evil when they believed themselves strong.” + +“And what do you get out of it?” + +For answer, he asked a question: + +“Did you ever play chess?” + +“Often, in many lives,” I answered. + +“Did you have an interest in the game?” + +“A great interest.” + +“Did you play for stakes?” + +“No.” + +“Then what interested you?” + +“Why, the game.” + +“Of course,” he said. “That is how I enjoy my game. I play to win, if I +can. When I do not win, I have had the pleasure of the game.” + +“And you played with that great man’s soul?” + +“As a cat plays with a mouse. I found in him an earnest spirit, with a +sore spot in his head and in his heart. He was an easy one.” + +“How did you go about it?” + +“By the usual method.” + +“And that is?” + +“Flattery.” + +“And he did not smell a rat?” + +“The rats were perfumed. He is an aesthete.” + +“Do you always perfume the rats?” + +“It isn’t always necessary. I perfumed yours.” + +“Yes,” I said, “with the patchouli of peace. But I have a keen scent.” + +“Yes, the Others have taught you too well.” + +“Did Nietzsche ever see you as I see you?” + +“He saw my distinguished face, and he felt the thrill of my power, and +he envied and desired to be like me. It is great sport when these +earnest mortals are ambitious to emulate me!” + +“And so you taught him Beyond Man?” + +“Yes, and I taught him to despise the One who was really Beyond Man.” + +“Then you are not really Beyond Man yourself?” + +“My head is. My other members are nearer the earth.” + +“Notwithstanding the dignity of your presence?” + +“Oh, there is a dignity in the earth and in what belongs to the earth!” + +“Did the German philosopher ever know you for what you are?” + +“Yes, toward the end, but then it was too late to undo my work.” + +“Then also at the end,” I exclaimed, “he saw the two forms of Beyond +Man, you and the Christ!” + +“Yes, he saw. The seeing drove him mad.” + +“And you have no remorse for your work?” + +“Remorse? What is that?” + +“Remorse is an emotion which men feel when they are conscious of having +done evil.” + +“An emotion that _men_ feel,” he repeated. “But I only feel those +emotions of men which give me pleasure in the feeling.” + +“Such as----” + +“You are really too curious and inquisitive!” + +“Granted, my curiosity and my inquisitiveness,” I said. “But it +interests me, this labor of a lifetime, a man’s lifetime, to make him +an instrument through which _all this_ could be produced,” and I +indicated by a gesture the battle line beneath us. + +His eyes were brilliant with fire as he answered: + +“What is the lifetime of a man in comparison to the glory of all this? +One might labor a thousand years and produce nothing in comparison with +this!” + +“It pleases you then, this slaughter?” + +“What a trifling question! It gratifies me, glorifies me, exalts +me--all this carnage of battle brought forth by me and my kind.” + +“And did you have all this in mind while you were preparing one man to +corrupt a nation by his writings?” + +“Yes. He was the one perfect instrument. None other could have served +our purpose so well--ambitious, dissatisfied, aristocratic, arrogant, +unloving in the broader sense, capable of infatuation and hence of +disenchantment, and last but not least, with eyes open to the vision.” + +“The vision of you?” + +“Yes. He saw me first in dreams, and admired me, and desired to emulate +me.” + +“And then you spoke to him of Beyond Man?” + +“Yes, and I used the old arguments that women were of small account; +that the love of woman stood in man’s way; that woman enslaved man +unless he enslaved her; that Nature was the devil, not the Great +Mother, and so was to be combatted as far as possible; that man rose to +Beyond Man by denying all that could influence him, including Nature, +and by asserting whatever gave him freedom, such as his own superiority +to all other beings, his mastery of them, his mastery of his own +thought, his mastery of good and evil, of fact and falsehood.” + +“A fine _combination_ of fact and falsehood, that teaching of +yours,” I said. + +“Of course,” he answered; “but what would you? Truth alone could never +have produced this.” And he swept with his long arm the line of battle +beneath us. + +“And what else did you teach your chosen disciple?” I asked. + +“I taught him all that he taught the world. Whenever he drove a woman’s +face from his heart, I scored a point and he thought himself nearer +Beyond Man. Whenever he swelled with pride and superiority, I scored +a point and he felt himself nearer Beyond Man. Whenever he read the +Gospels and sneered to himself at the humility of the so-called Son of +Man, I scored two points--one against him and one against your Christ.” + +“Thank you,” I said, “for enrolling me with the followers of the +Crucified One. I am such a follower.” + +He ignored my last remark, and proceeded: + +“I encouraged his wish to produce a new ideal of a leader, a new +Christ, an Antichrist, a hard-faced German Christ, who should not win +men by love and compassion, but by cruelty and hardening. Oh, I have +done that work well! Many a German has exalted my ideal to the place of +the Son of Mary. Many a German has put me in place of the Sun-God, and +hailed me as Beyond Man, though he was too cowardly to hail me frankly +_as_ Antichrist. Instead, he added my attributes to Christ and +called us by one name, and by that name he sought to destroy all pity +and compassion, both in himself and in others, sought to destroy all +love that stood in the way of his becoming like me. It was I who taught +him to exalt the cross as a symbol of cruelty, of sacrifice _to_ +himself, and not _of_ himself for the love of man.” + +He paused, and gazed out toward the stars that shone serenely above us. + +“You seem to me,” I said, “to be yourself conscious of the superiority +of Christ to Antichrist.” + +Again he ignored my remark, and continued the line of his own thought. + +“What intellectual pleasure it has given me, this transforming of a +Christian nation into monsters of egotism and cruelty to all things +_not their own_! The foreigner was to be hated, despised, used, +ridiculed, and whenever possible insulted. I taught them that such were +the ways of Beyond Man, that so was man surpassed.” + +“But why do you tell all this to me?” I asked. “Why do you thus lay +your cards upon the table, when you know that I hold a better hand?” + +The eyes he turned to me were smouldering lakes of flame. + +“Because I envy you,” he said. + +“Is that some new and more subtle attack upon me and the principles I +stand for?” + +The dark one laughed again, his sharp and mirthless laughter. + +“Frankly, no,” he said. “You no longer amuse me as an opponent.” + +“Which means----” + +“That I throw up the game in weariness--this is, for the present. +Already the souls I deluded are weary of me and my teaching. They have +seen a new light--some of them.” + +“Perhaps,” I said, “they have seen the light of the Christ, the true +Beyond Man.” + +“Perhaps,” he repeated. + +“And have you seen it, too?” + +“Faugh!” he said. “Are you ambitious to convert the devil?” + +“Ah, no!” + +Suddenly he turned to me: + +“Will you take me for a pupil?” + +“Again, no,” I answered. “You will make that request of some good +woman, with a better chance of deceiving her.” + +“So you know all the tricks?” + +“My Teacher has taught me much regarding the ways of your kind.” + +“Then I bid you good evening,” he said, and disappeared in the darkness. + + +World for which I write, I am telling you these things that you may +be armored with knowledge. When Satan asks you to convert him, beware +lest he convert you. When Satan points to Beyond Man, even to Christ, +be sure that his Christ is not Antichrist; be sure He is full of +compassion, that His heart bleeds for the woes and _weakness_ of +the world, that His crown of thorns is the mark of His sacrifice for +man, and not merely a becoming ornament. For, as He said: + +“By this shall all men know that ye are my disciples, if ye have love +one to another.” + +And also: + +“Take heed that no man deceive you. For many shall come in my name, +saying, I am Christ, and shall deceive many, * * * for there shall +arise false Christs, and false prophets, and shall show great signs and +wonders, insomuch that, if it were possible, they shall deceive the +very elect.” + + _June 2._ + + + + + LETTER XLVII + + THE NEW BROTHERHOOD + + +I WANT to speak of the new race, the coming race. The world is big with +child, and the present generation will look with wonder into the clear +eyes of the infant that shall redeem its parent. + +Pin your faith to the standard of the new race, work for it, make the +garments that it shall wear, and be ready for its coming. + +Already you are in touch with those who will help in its training, who +will be its teachers and guides. Give yourself also to the Great Work +that is planned for America in the coming days. No, you need not spend +all your time there; but do not remain away too long. Come and go, that +going away you may receive new impressions, and that coming back you +may bring the romance of older lands to entertain and inspire the new +land. + +But be ever loyal to the new. + +In the untrodden wilderness of America there is strength that shall +renew you from time to time. The cities of America will be redeemed by +the wilderness. The cities are too worldly. They have forgotten God. In +the open air, under the open sky, the message may be received by the +awakened soul. + +Send the children out to the wilderness to drink from the +uncontaminated springs. The water that flows through lead pipes may +refresh the body; but the water of mountain springs refreshes the soul. + +Behind the veil of Nature is the face of the Great Mother, and +though she does not always smile, yet her eyes are full of dreams +and mysteries. Nature is _not_ the devil. The devil is ever at +war with Nature. Nature is Isis, the Mother. Do not listen to the +blasphemers. They have confused the offices of Isis and of Typhon. It +is Isis, Nature, which shall bring forth Horus. Go back to Nature and +ask her for her message. She waits in the silence of the woods, and the +voice of the brook is her whisper; when the wind stirs in the trees it +is the rustling of her garments. The Mother is coming, O children of +the new race! In her arms you shall know refreshing rest, and in her +eyes shall you read the love that knows no selfishness, the bliss of +self-giving. + +Too long have you dwelt in cities, forgetting the Mother who bore you. +Too long have you lived without the magnetism of the kind earth in +contact with your naked feet. Too long have you trodden the dead, stony +and unmagnetic streets, that take from you but give nothing. Go back to +the woods and the streams. Read your destiny in the eyes of the stars +themselves--not merely on a printed chart. Jupiter has a message for +you which he will give only face to face, and so has the gentle Venus +and the eager Mars. Go to them for your lessons, in the quiet of the +hill-top alone with the Mother. + +Do not set up your temple in the market-place. Let your cathedral be +the aisles of the forest. + +Go to the city when you must, for it is always well to know the +opposite. The cathedral is stiller after the voice of the mart. + +Give honor where honor is due, to those who have led the children +forth to learn the mysteries of the primeval life. You grown-ups are +only taller children. Dance in a ring round the mulberry bush or round +the camp-fire. In the smell of burning wood the visions may come, as +I wrote you once before of your wood-fires in Paris. But what is a +wood-fire in a Paris grate compared with a camp-fire in the woods? Yes, +I was there the other night, on the outskirts of the gathering, and I +enjoyed it, too. + +My greetings to the Chief! + +The salvation of America lies in this wild-wood movement. Movement! +Well may you call it that. It is stirred by the very forces of the +earth herself; it is inspired by the race-spirit; it will go on and on, +in ever-widening circles. + +Whoever puts a stone in the way of this work will stumble over it +himself. Whoever brings Satanism into this movement will be devoured by +the demonic forces. There will not be enough left of him to grease two +sticks for the camp-fire. + +Rest you in peace. _We_ watch, and with us the souls of all the +thousands and tens of thousands and millions of native Americans, who +cannot go on to their rest until they have passed on the torch of the +Nature mysteries that were their heritage from their remote ancestors. + +They may be despised by those who despoiled them; but their forgiveness +shall redeem you, O America of the new race! + +Do you not know that many of those who made their escape into the rest +of the “happy hunting ground” are already coming back to incarnation in +the land they loved before? Look at the high cheek-bones of many of the +children, look at the eagle eyes and the straight taut forms. + +O America, you did a great wrong once in the pursuit of your destiny! +Yes, you did. Now strive to atone. Let the reincarnated red children +play in the wild woods, teach them the old code of honor and courage, +and they will work hand in hand with the reincarnated souls that +came by way of Europe, hand in hand shall they stand together in the +_Woodcraft Brotherhood_. + +My salutations to the Chief! + + _July 9._ + + + + + LETTER XLVIII + + IN THE CRUCIBLE + + +I AM still profoundly interested in the land that gave me birth. There +are dark days ahead for her, and the great soul of Abraham Lincoln is +very near to the helm of State at this moment, when peace and war hang +in the balance and the action of a day may decide the question. + +No irreparable injury must overtake this land. It is the great pioneer +of race freedom. As I told you months ago, one of America’s hands +threatens the other, and both threaten the whole body. + +May she keep peace so long as she can have peace with honor! But if the +dark day comes, may she face it with squared shoulders; and if her foes +be also those of her own household, it will not be the first time. A +man once prayed to be saved from his friends, declaring that he could +deal with his enemies himself. + +The stillness of the Germans in America at this moment is potent with +danger. If the hour comes when drastic action is necessary, they should +be invited to return into the fold of their naturalization, and those +who refuse should be dealt with severely, even to deportation. There +yet remains one country which might receive them for transportation to +that Fatherland they left--in quest of the freedom which they have now +abused and betrayed. + +The world is in the crucible, and Satan is in the laboratory with all +his cohorts. Our labor is to stand. It is not always easy to stand +steady. + +Be calm, and trust in the Motherland that shall yet give birth to the +new race, the synthesis of races. + + + + + LETTER XLIX + + BLACK MAGIC IN AMERICA + + +YOU have seen pretty clearly the methods employed by the evil forces to +balk progress, to destroy the work of centuries, to destroy the workers +for the future, and to frighten away those who seek to interfere with +this maliciousness. + +Notice that none of this is constructive work. It is all destructive, +all tearing down. Wars of construction have been engineered by angels; +but this is not a war of construction. + +Now let me tell you a few of the things against which the new race +in America will have to guard itself. As always where the forces of +progress are strong, the opposition is strong. I have written enough +about the good influences of this new birth; but I want to give a +few warnings, to analyze a few influences which are of a destructive +character. + +There is developing in America a great group of people who seek to gain +control of the desire-nature and the will of others, that they may use +them for their own purposes. These people are not all in one place, +they are not organized into one body but into many bodies, and some of +them are working quite independently. But in the astral world, and in +the language of us who work in that world, they are known as a “group.” + +They teach to those who will pay them, either in money or in service, +certain rules for controlling the mind of self and of others. They +teach the rudiments of astral knowledge to the many, and they teach +more advanced principles to the few. Some of their teachings are true, +some of their teachings are false; but there are few among them who +undertake any real discipline of character with their students. As one +profound teacher has said, for every step in psychic development, three +steps should be taken in the development of character. + +I need not name those who are most criminally active in teaching the +formulas of black magic to men and women who are utterly unfit to be +trusted with that knowledge. + +The question will naturally arise in the mind of the reader, What +_is_ black magic? I think I have given a similar definition +before, but you may restate it thus: + +Black magic is an attempt to gain control over the will or the astral +or the mind of one’s fellows, through means other than the normal +physical or the legitimate mental influence by word or pen; be it +through the use of the elementals of nature, artificial elementals, or +one’s own mental or elemental nature. + +Black magic may be deliberately used to influence, or black magic +may be deliberately used to injure; and its votaries often employ +_the substances of the body of the victim_, through which to gain +sympathetic control of his astral and etheric nature. + +I want to say to those who think it smart or amusing to fool with +these things: Beware of any man or of any woman who by _normal or +abnormal means_ seeks to get possession of the fluids of your body, +especially the blood and the other vital fluids. + +I shall not go into detail here. Those who accept my warning owe me no +thanks; those who disregard my warning do so at their own peril. + +It gives me no amusement thus to thrust myself between the evil forces +and their victims. By so doing I draw down upon myself the rage of +those forces that I thwart so far as I can. + +Be it so! I am competent to deal with them. And I want here to notify +anyone who thinks to destroy my work, or to destroy those who with +self-abnegation and selfless courage are helping me in the work of +trying to save my country from the forces of hell which are now +ravaging Europe--I want to notify any evil magician who is interested +in this matter, that if he gets in the way of my resolve it will be he +who will suffer and not I. + +The ring which I and the Masters behind me draw round our workers can +be passed with evil intent only at the peril of the one who passes. + +This is no threat to use evil magic. We do not use evil magic. But we +know how to deflect a malicious current from its chosen victim, so that +it returns with overwhelming force upon its own source. + +And I also want to say to those who in their ignorance or wantonness +allow themselves to be used as catspaws to draw the devil’s chestnuts +from the fire, that fire will burn, and that the devil’s hot chestnuts +stick to the fingers. + +This is an unpleasant subject. I will now leave it. + + +Let me talk to those who are ignorant of these matters, and most people +are ignorant--even those who have “studied psychism.” + +Many an innocent (or half-innocent) soul has been driven nearly insane +by the pressure of the evil thoughts of others, by the will-driven +thoughts of others. + +Let me advise such not further to weaken themselves by fear, but to +strengthen themselves by prayer. + +I have said that there is a god and a devil in every one of you. Turn +to the god for protection from the devil. If there were no devil in +you, the devils of others could not harm you. Remember that. + +Set your own devil to serve your own god. + +If you want to use signs and symbols, meditate on the cross of Christ. +The cross of Christ is profound enough for a lifetime’s meditation. + +Do not use evil magic to protect yourself against evil magic. Call on +the god within to send evil back to its source. + +Protect yourself before sleep by prayer to your god for protection. The +evil workers can sometimes reach your soul in sleep when they cannot +reach you while awake. The child’s prayer, “Now I lay me down to sleep, +I pray the Lord my soul to keep,” is more potent than a magician’s +spells. + +Childish, you say? Yes, but I am writing now for those who are children +in these things, be they seven or seventy. + +Of all countries on earth, America is the most abysmally ignorant of +the dangers of evil magic. Be willing to be children until you acquire +adult knowledge of these subjects. + +“I am in no danger, for I understand these things,” is often said with +self-gratulation by these who are in the very grip of the evil forces. +Truly, a little knowledge is a dangerous thing. + + +If you want an added protection, my children, guard your own evil +passions and resentful thoughts, your jealous emotions and unkind +criticism of others. The devils ride on waves of anger and resentment. + +Beware also of temptations, remembering that young souls are tempted +through their faults, greater souls through their virtues. + +Be not deceived into saying there is no evil. Evil is--so long as good +is. + +“Beyond good and evil” is a state to which few of you can aspire, and +you have no conception of it. But “beyond good and evil” is a mighty +slogan for the temptation and bewilderment of vain souls. + +When you are really beyond good and evil you will not gossip about your +neighbors, nor envy them their charm or their possessions, nor try to +use them for your own ends, nor worry lest some evil person shall do +you harm, nor twist your faults till they seem virtues, nor deceive +yourself as to your motives. + +Examine yourselves, my children. Look for your faults. If you can find +no fault in yourself, hang your harp on the nearest willow, for your +progress is at an end. + +Man progresses through recognizing his faults, through transmuting them +and transcending them. If you are perfect, this world is no place for +you. + +“Beyond good and evil,” indeed! + +Judge not, that ye be not judged. But do not flirt with the devil to +prove that you judge him not. + +Yes, all men are your brothers, even bad men. Attend to your own +affairs, and leave the issue with God. + +This much to you, dear children of the world, from my vantage place +above your passions. + + _July 25._ + + + + + LETTER L + + THINGS TO REMEMBER + + +THAT the contents of this book may become the possession of those who +want it, I will now bring it to a close. + +One might go on writing forever about the astral incidents of this war, +and not exhaust the subject. What I have been able to give is a mere +sketch, a few incidents, a few suggestions. + +These things, however, bear in mind: + +That there are angels as well as devils in the neighborhood of the +battlefields. + +That those who see the war from above see causes as well as effects, +and from those causes can draw sane conclusions based on a richer fund +of data than that available to the men of earth. + +That war, like everything else, has its rhythms. Do not be discouraged +when the pressure of battle bears heavily on the side that you call +yours. If your side went forward too quickly, you would need to look +for a violent reaction, as in the retreat from the outskirts of Paris. + +That though evil is a necessity so long as good exists, though evil is +the other pole of the magnet, yet it is the duty of those who desire +to walk the White Road ever to do battle for the right. And this is no +repudiation of the saying of the Christ, “Resist not evil.” A paradox, +you say? Great wisdom is locked in paradoxes, for those who have the +key. The existence of evil gives greater strength to good. This is the +Kali Yuga, as the Hindoos say. + +That this war is an attempt of the personal evil forces to destroy +mankind. A former attempt was made in Europe before the so-called Dark +Ages, but the Renaissance followed and restored the balance. + +That man has in himself both the Christ principle and the demonic +principle; that will is free, and that man can make his choice between +them. + +That new races are born of revolutions and wars. He that hath ears to +hear, let him hear. + +That though I may have a wider sight than you, I do not know +everything. I draw conclusions from premises, the same as you do. +I predict the probable effects of causes known to me; but a sudden +irruption of free and erratic will sets up a new cause, and my +calculation has to be made afresh. My predictions are not the result of +divine omniscience. I see further than you, that is all. My logic may +be no better than yours. For instance, when we drove back the forces +of evil during the early months of the war, I forgot the Law of Rhythm +that would enable them to roll forward again when they had generated +another supply of strength. Even devils generate their own strength. +Yes, they too are Units of Force, and must be figured on as such. I +shall not make that mistake again. + + +My Teacher, who stands beside me at this moment, directs me to say +that even the Masters do not know everything. As my vision is wider +than yours, so their vision is wider than mine; but they cannot always +see what goes on in the farthest stars. They invite you to become like +them; but they know that you are held by rhythmic law, and that for +every two steps you take toward them, you will fall back at least +one step. That you do not fall back two steps is because of your free +will, and because of that greater rhythm which urges mankind to the +flood-tide. Each achievement is a ripple in a larger wave which you +cannot always see. + +I have been requested to write further of my Teacher, but my Teacher +wishes to remain in the background. I may tell you this, however, O +world! my Teacher still has a physical body and walks the earth as a +man. He works in both the material and the astral worlds, and in higher +worlds beyond them, and the purposes of his life are outside your +comprehension. He is a servant of the Law, and his joy is in working +_with_ the Law. The Black Masters, for there are Black Masters, +work against the Law. I have told you of my conversations with one of +them, and have given you a hint as to his methods. + +When you are strong, you need not fear the Black Masters. You may pass +the time of day with them, as I do. They are far more afraid of me than +I am of them. I do not go out of my way if I see one coming. I find +them rather diverting, though I recognize the tragedy of their lot. +They fill a terrible office, which must be filled, and their sufferings +are great. They are the erring brothers of the White Masters. In the +beginning they were trained in the same school; but the great “moment +of choice” came, and the evil ones _separated themselves_ from +their source. The White Masters do not seek to destroy them, knowing +that in the end they will destroy themselves. Why waste effort in +striving to hurry the sunset? + +Do not let the black Masters and their servants mislead you, and avoid +them if you can until you are stronger than they. But when you are +stronger than they, you have nothing to fear from them. + +When they cannot affect you directly, they strive to affect you through +those you love. Be at peace. You are not your brother’s keeper. If +your brother delights in the devil, let him have the pleasure of his +preference. Will is free. + +Give testimony of the truth that is in you; but do not attempt to +muzzle the hounds that bay the summons to the witches’ sabbath. + +Enter the Holy Temple and shut the door; then invoke the angels. The +baying of the hounds cannot drown the music of the angel voices. + +Be still, and know that God is God. + + +A great day is dawning for America--after a time of trial. The sun +will rise from behind a bank of clouds; but in the freshness of the +dawn much labor will be done for the new race, and for the Brotherhood +of races. All over America movements will be started for the training +and perfecting of mankind. Give them your help, for thus you will be +working with the Law. Thus you will be learning the first lessons in +the school of the White Masters, whose watchword is Service. + + +Though I am not going far away this time, yet I leave you my blessing, +O world that I have labored and suffered for--far more than you know +during the last hard year. + +And I want to thank the world for its great interest in my former book, +“Letters from a Living Dead Man.” Yes, I am living still, and am far +more alive than when I wrote for you before. Little by little I am +growing into an intensity of life which I could not have imagined when +I walked the earth as a man among men. + +In these War Letters from the other world I have tried to give you +glimpses of that intenser life which I lead now, after my return from +the journey among the stars. I had thought to tell you of that journey +when I should return again; but the story would not have been so +instructive at the present time as this story of the war in the astral +world. For you are nearer the astral world than you are to the stars, +and until you learn the a-b-c you cannot read and understand romances. + +I am only a humble servant of the Law, a learner in the school of those +who are wiser than I. To get, I must give. To learn, I must teach. To +go forward, I must try to bring you forward with me. + +It has seemed to me that what the world needed most at the present time +was a knowledge of the mysteries behind this war. I have been an unseen +soldier in this war, in which I have received many a wound. I have +had my nights of vigil and my days of labor; but they have given me a +strength that I could not otherwise have gained. I am strong because I +have served. + +Serve you, and the reward will come in due season! + +I am going to rest now for a little while, because I have another +service to perform in the near future. + +I shall not go far away. + +“X.” + + _July 28, 1915._ + + + THE END. + + + + + =TRANSCRIBER’S NOTES= + +Simple typographical errors have been silently corrected; unbalanced +quotation marks were remedied when the change was obvious, and +otherwise left unbalanced. + +Punctuation, hyphenation, and spelling were made consistent when a +predominant preference was found in the original book; otherwise they +were not changed. + + + + + +*** END OF THE PROJECT GUTENBERG EBOOK WAR LETTERS FROM THE LIVING DEAD MAN *** + + + + +Updated editions will replace the previous one—the old editions will +be renamed. + +Creating the works from print editions not protected by U.S. copyright +law means that no one owns a United States copyright in these works, +so the Foundation (and you!) can copy and distribute it in the United +States without permission and without paying copyright +royalties.

Information about the Mission of Project Gutenberg™ + +Project Gutenberg™ is synonymous with the free distribution of +electronic works in formats readable by the widest variety of +computers including obsolete, old, middle-aged and new computers. It +exists because of the efforts of hundreds of volunteers and donations +from people in all walks of life. + +Volunteers and financial support to provide volunteers with the +assistance they need are critical to reaching Project Gutenberg™’s +goals and ensuring that the Project Gutenberg™ collection will +remain freely available for generations to come. In 2001, the Project +Gutenberg Literary Archive Foundation was created to provide a secure +and permanent future for Project Gutenberg™ and future +generations. To learn more about the Project Gutenberg Literary +Archive Foundation and how your efforts and donations can help, see +Sections 3 and 4 and the Foundation information page at www.gutenberg.org. + +Section 3. Information about the Project Gutenberg Literary Archive Foundation + +The Project Gutenberg Literary Archive Foundation is a non-profit +501(c)(3) educational corporation organized under the laws of the +state of Mississippi and granted tax exempt status by the Internal +Revenue Service. The Foundation’s EIN or federal tax identification +number is 64-6221541. Contributions to the Project Gutenberg Literary +Archive Foundation are tax deductible to the full extent permitted by +U.S. federal laws and your state’s laws. + +The Foundation’s business office is located at 809 North 1500 West, +Salt Lake City, UT 84116, (801) 596-1887. Email contact links and up +to date contact information can be found at the Foundation’s website +and official page at www.gutenberg.org/contact + +Section 4. Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg™ depends upon and cannot survive without widespread +public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine-readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To SEND +DONATIONS or determine the status of compliance for any particular state +visit www.gutenberg.org/donate. + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg web pages for current donation +methods and addresses. Donations are accepted in a number of other +ways including checks, online payments and credit card donations. To +donate, please visit: www.gutenberg.org/donate. + +Section 5. General Information About Project Gutenberg™ electronic works + +Professor Michael S. Hart was the originator of the Project +Gutenberg™ concept of a library of electronic works that could be +freely shared with anyone. For forty years, he produced and +distributed Project Gutenberg™ eBooks with only a loose network of +volunteer support. + +Project Gutenberg™ eBooks are often created from several printed +editions, all of which are confirmed as not protected by copyright in +the U.S. unless a copyright notice is included. Thus, we do not +necessarily keep eBooks in compliance with any particular paper +edition. + +Most people start at our website which has the main PG search +facility: www.gutenberg.org. + +This website includes information about Project Gutenberg™, +including how to make donations to the Project Gutenberg Literary +Archive Foundation, how to help produce our new eBooks, and how to +subscribe to our email newsletter to hear about new eBooks. + + +
