It seems difficult for those who are accustomed only to the ordinary and somewhat materialistic lines of thought of the nineteenth century, to believe in and realize fully a condition of perfect consciousness apart from the physical body. Every Christian, at any rate, is bound by the very foundations of his creed to believe that he possesses a soul; but if you suggest to him the possibility that that soul may be a sufficiently real thing to become visible under certain conditions apart from the body either during life or after death, the chances are ten to one that he will scornfully tell you that he does not believe in ghosts, and that such an idea is nothing but an anachronistic survival of an exploded mediaeval superstition.
If, therefore, we are at all to comprehend the work of the band of invisible helpers, and perchance ourselves to learn to assist in it, we must shake ourselves free from the trammels of contemporary thought on these subjects, and endeavour to grasp the great truth (now a demonstrated fact to many among us) that the physical body is in simple truth nothing but a vehicle or vesture of the real man. It is put off permanently at death, but it is also put off temporarily every night when we go to sleep — indeed the process of falling asleep consists in this very action of the real man in his astral vehicle slipping out of the physical body.
Again I repeat, this is no mere hypothesis or ingenious supposition. There are many among us who are able to perform (and do perform every day of their lives) this elementary act of magic in full consciousness — who pass from one plane to the other at will; and if that is clearly realized, it will become apparent how grotesquely absurd to them must appear the ordinary unreasoning assertion that such a thing is utterly impossible. It is like telling a man that it is impossible for him to fall asleep, and that if he thinks he has ever done so he is under a hallucination.
Now the man who has not yet developed the link between the astral and physical consciousness is unable to leave his denser body at will, or to recollect most of what happens to him while away from it; but the fact nevertheless remains that he leaves it everytime he sleeps, and may be seen by any trained clairvoyant either hovering over it or wandering about at a greater or less distance from it, as the case may be.
The entirely undeveloped person usually floats close above his physical body, scarcely less asleep than it is, and comparatively shapeless and inchoate, and it is found that he cannot be drawn away from the immediate neighbourhood of that physical body without causing serious discomfort which would in fact awaken it. As the man evolves, however, his astral body grows more definite and more conscious, and so becomes a fitter vehicle for him. In the case of the majority of intelligent and cultured people the degree of consciousness is already very considerable, and a man who is at all spiritually developed is as fully himself in that vehicle as in this denser body.
But though he may be fully conscious on the astral plane during sleep, and able to move about on it freely if he wishes to do so, it does not yet follow that he is ready to join the band of helpers. Most people at this stage are so wrapped up in their own train of thought — usually a continuation of some line taken up in waking hours — that they are like a man in a brown study, so much absorbed as to be practically entirely heedless of all that is going on about them. And in many ways it is well that this is so, for there is much upon the astral plane which might be unnerving and terrifying to one who had not the courage born of full knowledge as to the real nature of all that he would see.
Sometimes a man gradually rouses himself out of this condition — wakes up to the astral world around him, as it were; but more often he remains in that state until someone who is already active there takes him in hand and wakens him. This is, however, not a responsibility to be lightly undertaken, for while it is comparatively easy thus to wake a man up on the astral plane, it is practically impossible, except by a most undesirable exercise of mesmeric influence, to put him to sleep again. So that before a member of the band of workers will thus awaken a dreamer, hemust fully satisfy himself that the man's disposition is such that he will make good use of the additional powers that will then be put into his hands, and also that his knowledge and his courage are sufficient to make it reasonably certain that no harm will come to him as a result of the action.
Such awakening so performed will put a man in a position to join if he will the band of those who help mankind. But it must be clearly understood that this does not necessarily or even usually bring with it the power of remembering in the waking consciousness anything which has been done. That capacity has to be attained by the man for himself, and in most cases it does not come for years afterwards — perhaps not even in the same life. But happily this lack of memory in the body in no way impedes the work out of the body; so that, except for the satisfaction to a man of knowing during his waking hours upon what work he has been engaged during his sleep, it is not a matter of importance. What really matters is that the work should be done — not that we should remember who did it.
