our strange adventures. You ask, why in the Arctic, why underground? Our work demands that the mind shall be isolated from the contemporary human world; only in a remote land, and beneath its surface, can we escape the telepathic influence of the world-population. Our telepathic intercourse is based on the transmission and reception of ethereal vibrations from brain to brain. Normally our powers of reception are kept under strict control, so that we receive messages only when we will. But, in the peculiar trance which is our medium for exploring the past, this control fails; so that, unless the explorer is isolated, his mind is lashed like a pond in which torrential rain is falling.
When I had entered my room and shut my door, I went out into my garden and walked up and down for a while, preparing my mind for its adventure. I then brought out from the room a drawer full of rolls of microscopically figured tape, which in my world take the place of books. In normal circumstances these little rolls work by systematically interrupting the radiation of a special instrument. This radiation penetrates the brain of the ‘reader’, and is interpreted telepathically by the telepathic organ of his brain. But since in the catacombs no radiation other than the normal solar wave-lengths is permitted, we explorers have to learn actually to read the rolls, with the aid of a microscope.
I now spent many hours lying on the turf in the sunshine, reading about the epoch which I was to visit. After a while I re-entered the room and pressed a button in the wall. A tray appeared, bearing an appetizing meal. When I had finished this, and dismissed the tray, I returned to the garden and my studies. For a period equivalent to about ten days I lived in this manner, studying, meditating, eating occasionally, but sleeping not at all. Sometimes I would break off my studies to tend my garden. Frequently I would swim about in the pond among the bushes. But for the most part I merely browsed on my books or on my own records of the past. Toward the end of this period of preparation, I grew desperately sleepy. To keep myself awake, I had to walk up and down more and more, and my dips in the pond became more frequent. It was almost time to be gone. I drew my little bed out into the garden and made it ready to receive me. I pressed another button, which would make day slowly become night. I took a final dip and a final walk, then staggered to my bed and lay down in the twilight.
But even yet I must not sleep. Instead, I concentrated my attention on the recurrent rise and fall of my own breathing, and on the nature of time. This process I had to maintain for about thirty hours, without food or sleep or any respite. Toward the end of this period, had you seen me, you would have said that I was at last falling asleep, and finally you would have declared me to be in a very profound slumber. And so in a manner I was, save that a single organ in my brain, usually dormant, was now intensely active, and preparing to take possession of my whole body as soon as my brain should have been refreshed by its deep sleep. After a couple of days of unconsciousness I did indeed wake, but not to the familiar surroundings.
For months, even years or decades, my body might now remain inert upon its bed, save for periodic risings to perform its natural functions of eating, drinking and excretion. Frequently also it would walk for hours at a time in the garden or bathe in the pond. But these activities would be carried out in complete abstraction, and had any one spoken to me at these times, I should have been unaware. For the higher centres of my brain were wholly possessed by the past. To any one watching me during these routine activities, I should have appeared as a sleep-walker. At these times, no less than during the long periods of quiescence on my bed, the observer would have seen that my face, and sometimes my whole body, was constantly influenced by emotion and thought. For during the whole trance, of course, my brain would be experiencing sequences of events in the remote past, and my whole body would respond to these experiences with my normal emotional reactions. Thus to the observer I should appear to be asleep and dreaming, save that my expressions would be far more definite and systematic than those of a dreamer.
Here I will mention one point of philosophical interest. The duration of the trance has no relation to the duration of the past events observed. Thus I might lie in my comfortable prison for a year, and in that time I might observe many years of past events, or many thousands of years, or even the whole span of man’s history. The length of the trance depends only on the complexity of the matter observed. I might for instance spend a year in observing an immense number of simultaneous events which took only a few minutes to occur. Or I might cover the whole life of one individual in far more detail than was afforded by his own consciousness of his life-story. Or I might sweep through whole epochs, tracing out only some one simple thread of change. In fact the length of the trance depends simply on the brain’s capacity to assimilate, not upon the actual duration of the events observed.
When as much material has been gathered as can be conveniently grasped, the explorer gradually withdraws his attention from the past. He then sinks into an undisturbed sleep which may last for several weeks. During this phase his body shows none of that ceaseless emotional expression which is characteristic of the main trance. It lies inert, as though stunned. Finally the explorer’s attention begins to concentrate itself again, and to revert once more to his own body and its surroundings. He wakes, and lies for a while passively accepting the new visual impressions. He then lives in his apartments for months or years recording his experiences in rough notes, to be organized at a later date. Sometimes, when this process is finished, he chooses to return at once, without respite, to the past for further data. Sometimes he leaves his room to confer with other workers. Sometimes he decides to drop his work and return to the contemporary world for refreshment.
2. DIFFICULTIES AND DANGERS
How it comes that at the moment of the onset of the trance the explorer is freed from the limitations of his own date and place I cannot tell you. Suffice it that the process involves both a special organ in the brain and a special technique, which has to be learned through a long apprenticeship. In that moment of awakening the worker has seemingly a confused experience of all the great successive epochal phases of the human spirit, up to his own date. But as the content of that supreme moment almost wholly escapes his memory as soon as it is past, it is impossible to say anything definite about it. He seems, indeed, to see in a flash, as though from another dimension of time, the whole historical order of events. Of course, he sees them only schematically. Their vast complexity of detail cannot be grasped in an instantaneous view. What he experiences can only be described (unintelligibly I fear) as a summation of all happening, of all physical, mental and spiritual flux. One is tempted to say also that he is aware of the human aspect of this flux as a vast slumber of the spirit, punctuated with moments of watchfulness, a vast stagnation troubled here and there with tremors of tense activity. Though all this is seen in an instant, it does not appear static, but alive with real passage and change.
This sublime moment must not be permitted to endure, for it is lethal. Immediately the explorer must begin to select that part of the historical order which he desires to study. To do this he must adopt the fundamental attitude of mind, or temperamental flavour, which he knows to be distinctive of the desired period. This process demands very great skill, and involves a host of uncouth and nerve-racking experiences. As soon as he begins to succeed in assuming the appropriate mental attitude, all the periods save that which he has chosen fade out of his consciousness, and the chosen period becomes increasingly detailed. He has then to specialize his mental attitude still further, so as to select a particular phase or group-culture within his period. And this specialization he may carry further again, till he has brought himself into the mind of some particular individual at a particular moment. Having once gained a footing in the individual mind, he can henceforth follow all its experiences from within; or, if he prefers, he can remain in one moment of that mind, and study its microscopic detail.
Such is the essence of our method. First we have to attain the momentary glimpse of eternity, or, more precisely, to take up for one instant the point of view of eternity. Then by imagination and sympathy we have to re-enter the stream of time by assuming the fundamental form of the minds or the mind that we wish to observe. In this process we have to work by means of a very delicate ‘selectivity’, not wholly unlike that physical selectivity which you exercise when you pick up ethereal messages on a particular wave-length. But this process of picking up past minds
