When the power of bringing over the consciousness is perfectly acquired the pupil will have the advantage of the use of all the astral faculties, not only while out of his body during sleep or trance, but also while fully awake in ordinary physical life. It has been the custom of some Theosophists to speak with scorn of the astral plane, and treat it as entirely unworthy of attention; but that seems to me a mistaken view. Assuredly, that at which we have to aim is the life of the spirit, and it would be disastrous for any student to neglect that higher development and rest satisfied with the attainment of astral consciousness. There have been some whose karma was such as to enable them to develop the higher mental faculties first of all—to overleap the astral plane for the time, as it were; but this is not the ordinary method adopted by the Masters of the Wisdom with their pupils. Where it is possible it no doubt saves trouble, for the higher usually includes the lower; but for most of us such progress by leaps and bounds has been forbidden by our own faults or follies in the past; all that we can hope for is to win our way slowly step by step, and since this astral plane lies next to our world of denser matter, it is generally in connection with it that our earliest super-physical experiences take place. It is therefore of deep interest to those of us who are but beginners in these studies, and a clear comprehension of its mysteries may often be of great importance to us, by enabling us not only to understand many of the phenomena of the seance-room, of haunted houses, etc., which would otherwise be inexplicable, but also to guard ourselves and others from possible dangers.
The first conscious introduction to this remarkable region comes to people in various ways. Some only once in their whole lives under some unusual influence become sensitive enough to recognize the presence of one of its inhabitants, and perhaps, because the experience does not repeat itself, they may come in time to believe that on that occasion they must have been the victims of hallucination. Others find themselves with increasing frequency seeing and hearing something to which those around them are blind and deaf; others again—and perhaps this is the commonest experience of all—begin to recollect with greater and greater clearness that which they have seen or heard on that other plane during sleep. It must be understood that the power of objective perception upon all the planes undoubtedly lies latent in every man, but for most of us it will be a matter of long and slow evolution before our consciousness can fully function in those higher vehicles.
With regard to the astral body the matter is, however, somewhat different, for in the case of all the cultured people belonging to the more advanced races of the world, the consciousness is already perfectly capable not only of responding to all vibrations communicated to it through astral matter, but also of using its astral body definitely as a vehicle and instrument. Most of us, then, are awake on the astral plane during the sleep of the physical body, and yet we are generally very little awake to the plane, and are consequently conscious of our surroundings there only vaguely, if at all. We are still wrapped up in our waking thoughts and our physical-plane affairs, and we pay scarcely any attention to the world of intensely active life that surrounds us. Our first step, then, is to shake off this habit of thought, and learn to see that new and beautiful world, so that we may be able intelligently to work in it. Even when that is achieved, it does not necessarily follow that we shall be able to bring over into our waking consciousness any recollection of those astral experiences. But that question of physical-plane remembrance is an entirely different matter, and does not in any way affect our power to do excellent astral work.
Among those who make a study of these subjects, some try to develop the astral sight by crystal-gazing or other methods, while those who have the inestimable advantage of the direct guidance of a qualified teacher will probably be aroused to full consciousness upon that plane for the first time under his special protection, which will be continued until, by the application of various tests, he has satisfied himself that each pupil is proof against any danger or terror that he is likely to encounter. But however it may occur, the first actual realization that we are all the while in the midst of a great world full of active life, of which most of us are nevertheless entirely unconscious, cannot but be a memorable epoch in a man's existence. So abundant and so manifold is this life of the astral plane that at first it is absolutely bewildering to the neophyte; and even for the more practised investigator it is no easy task to attempt to classify and to catalogue it. If the explorer of some unknown tropical forest were asked not only to give a full account of the country through which he has passed, with accurate details of its vegetable and mineral productions, but also to state the genus and species of every one of the myriad insects, birds, beasts, and reptiles which he had seen, he might well shrink appalled at the magnitude of the undertaking. Yet even this affords no parallel to the embarrassments of the psychic investigator, for in his case matters are further complicated, first by the difficulty of correctly translating from that plane to this the recollection of what he has seen, and secondly by the utter inadequacy of ordinary language to express much of what he has to report.
However, just as the explorer on the physical plane would probably commence his account of a country by some sort of general description of its scenery and characteristics, so it will be well to begin this slight sketch of the astral plane by endeavouring to give some idea of the scenery which forms the background of its marvellous and ever-changing activities. Yet here at the outset an almost insuperable difficulty confronts us in the extreme complexity of the matter. All who see fully on that plane agree that to attempt to call up a vivid picture of this astral scenery before those whose eyes are as yet unopened is like speaking to a blind man of the exquisite variety of tints in a sunset sky—however detailed and elaborate the description may be, there is no certainty that the idea presented before the hearer's mind be an adequate representation of the truth.
SCENERY
FIRST of all, then, it must be understood that the astral plane has seven subdivisions, each of which has its corresponding degree of materiality and its corresponding condition of matter. Although the poverty of physical language forces us to speak of these subplanes as higher and lower, we must not fall into the mistake of thinking of them (or indeed of the greater planes of which they are only subdivisions) as separate localities in space—as lying above one another like shelves of a book-case or outside one another like the coats of an onion. It must be understood that the matter of each plane or subplane interpenetrates that of the plane or subplane below it, so that here at the surface of the earth all exist together in the same space, although it is true that the higher varieties of matter extend further away from the physical earth than the lower.
So when we speak of a man as rising from one plane or subplane to another, we do not think of him as necessarily moving in space at all, but rather as transferring his consciousness from one level to another—gradually becoming unresponsive to the vibrations of one order of matter, and beginning instead to answer to those of a higher and more refined order; so that one world with its scenery and inhabitants seems to fade slowly away from his view, while another world of a more elevated character dawns upon him in its stead. Yet there is a point of view from which there is a certain justification for the use of the terms "higher" and "lower", and for the comparison of the planes and subplanes to concentric shells.
Matter of all the subplanes is to be found here on the surface of the earth, but the astral plane is much larger than the physical, and extends some thousands of miles above its surface. The law cf gravitation operates on astral matter, and if it were possible for it to be left entirely undisturbed it would probably settle into concentric shells. But the earth is in perpetual motion, both of rotation and revolution, and all kinds of influences and forces are continually rushing about, so this ideal condition of rest is never attained, and there is much intermingling. Nevertheless it remains true that the higher we rise the less of the denser matter do we find. We have a fair analogy on the physical plane.
Earth, water and air—the solid, the liquid and the gaseous—all exist here on the surface but broadly speaking it is true to say the solid matter lies lowest, the liquid
