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 before those whose eyes are as yet unopened a vivid picture of this astral scenery 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 will 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. Now numbering these from the highest and least material downwards, we find that they naturally fall into three classes, divisions 1, 2 and 3 forming one such class, and 4, 5 and 6 another, while the seventh and lowest of all stands alone. The difference between the matter of one of these classes and the next would be commensurable with that between a solid and a liquid, while the difference between the matter of the subdivisions of a class would rather resemble that between two kinds of solid, such as, say, steel and sand. Putting aside for the moment the seventh, we may say that divisions 4, 5 and 6 of the astral plane have for their background the physical world we live in and all its familiar accessories. Life on the sixth division is simply our ordinary life on this earth, minus the physical body and its necessities; while as it ascends through the fifth and fourth divisions it becomes less and less material, and is more and more withdrawn from our lower world and its interests.

The scenery of these lower divisions, then, is that of the earth as we know it: but it is also very much more; for when looked at from this different standpoint, with the assistance of the astral senses, even purely physical objects present a very different appearance. As has already been mentioned, they are seen by one whose eyes are fully opened, not as usual from one point of view, but from all sides at once—an idea in itself sufficiently confusing; and when we add to this that every particle in the interior of a solid body is as fully and clearly visible as those on the outside, it will be comprehended that under such conditions even the most familiar objects may at first be totally unrecognizable. Yet a moment's consideration will show that such vision approximates much more closely to true perception than does physical sight. Looked at on the astral plane, for example, the sides of a glass cube would all appear equal, as they really are, while on the physical plane we see the further side in perspective—that is, it appears smaller than the nearer side, which is, of course, a mere illusion. It is this characteristic of astral vision which has led to its sometimes being spoken of as sight in the fourth dimension—a very suggestive and expressive phrase. But in addition to these possible sources of error matters are further complicated by the fact that astral sight cognizes forms of matter which, while still purely physical, are nevertheless invisible under ordinary conditions. Such, for example, are the particles composing the atmosphere, all the various emanations which are always being given out by everything that has life, and also four grades of a still finer order of physical matter which, for want of more distinctive names, must all he described as etheric. The latter form a kind of system by themselves, freely interpenetrating all other physical matter; and the investigation of their vibrations and the manner in which various higher forces affect them would in itself constitute a vast field of deeply interesting study for any man of science who possessed the requisite sight for its examination.

Even when our imagination has fully grasped all that is comprehended in what has already been said, we do not yet understand half the complexity of the problem; for besides all these new forms of physical matter we have to deal with the still more numerous and perplexing subdivisions of astral matter. We must note first that every material object, every particle even, has its astral counterpart; and this counterpart is itself not a simple body, but is usually extremely complex, being composed of various kinds of astral matter. In addition to this each living creature is surrounded with an atmosphere of its own, usually called its aura, and in the case of human beings this aura forms of itself a very fascinating branch of study. It is seen as an oval mass of luminous mist of highly complex structure, and from its shape has sometimes been called the auric egg. Theosophical readers will hear with pleasure that even at the early stage of his development at which the pupil begins to acquire this astral sight, he is able to assure himself by direct observation of the accuracy of the teaching given through our great founder, Madame Blavatsky, on the subject of some at least of the seven principles of man. In regarding his fellow-man he no longer sees only his outer appearance; exactly co-extensive with that physical body he clearly distinguishes the etheric double, which in Theosophical literature has usually been called the Linga Sharîra; while the Jîva, as it is absorbed and specialized into Prâna, as it circulates in rosy light throughout the body, as it eventually radiates from the healthy person in its altered form, is also perfectly obvious. Most brilliant and most easily seen of all, perhaps, though belonging to quite a different order of matter—the astral—is the kâmic aura, which expresses by its vivid and ever-changing flashes of colour the different desires which sweep across the man's mind from moment to moment. This is the true astral body. Behind that, and consisting of a finer grade of matter—that of the rûpa levels of Devachan—lies the devachanic body or aura of the lower Manas, whose colours, changing only by slow degrees as the man lives his life, show the disposition and character of the personality; while still higher and infinitely more beautiful, where at all clearly developed, is the living light of the Kârana Sharîra, the aura or vehicle of the higher Manas, which shows the stage of development of the real Ego in its passage from birth to birth. But to see these the pupil must have developed something more than mere astral vision.

It will save the student much trouble if he learns at once to regard these auras not as mere emanations, but as the actual manifestation of the Ego on their respective planes—if he understands that it is the auric egg which is the real man, not the physical body which on this plane crystallizes in the middle of it. So long as the reincarnating Ego remains upon the plane which is his true home in the arûpa levels of Devachan, the body which he inhabits is the Kârana Sharîra, but when he descends into the rûpa levels he must, in order to be able to function upon them, clothe himself in their matter; and the matter that he thus attracts to himself furnishes his devachanic or mind-body. Similarly, descending into the astral plane he forms his astral or kâmic body out of its matter, though of course still retaining all the other bodies, and on his still further descent to this lowest plane of all the physical body is formed in the midst of the auric egg, which thus contains the entire man.
