But let the surface of the water be ruffled by the wind and what do we find then? A reflection still, certainly, but so broken up and distorted as to be quite useless or even misleading as a guide to the shape and real appearance of the objects reflected. Here and there for a moment we might happen to get a clear reflection of some minute part of the scene—of a single leaf from a tree, for example; but it would need long labour and considerable knowledge of natural laws to build up anything like a true conception of the object reflected by putting together even a large number of such isolated fragments of an image of it.
Now in the astral plane we can never have anything approaching to what we have imaged as a still surface, but on the contrary we have always to deal with one in rapid and bewildering motion; judge, therefore, how little we can depend upon getting a clear and definite reflection. Thus a clairvoyant who possesses only the faculty of astral sight can never rely upon any picture of the past that comes before him as being accurate and perfect; here and there some part of it may be so, but he has no means of knowing which it is. If he is under the care of a competent teacher he may, by long and careful training, be shown how to distinguish between reliable and unreliable impressions, and to construct from the broken reflections some kind of image of the object reflected; but usually long before he has mastered those difficulties he will have developed the mental sight, which renders such labour unnecessary.
On the next plane, which we call the mental, conditions are very different. There the record is full and accurate, and it would be impossible to make any mistake in the reading. That is to say, if three clairvoyants possessing the powers of the mental plane agreed to examine a certain record there, what would be presented to their vision would be absolutely the same reflection in each case, and each would acquire a correct impression from it in reading it. It does not however follow that when they all compared notes later on the physical plane their reports would agree exactly. It is well known that if three people who witness an occurrence down here in the physical world set to work to describe it afterwards, their accounts will differ considerably, for each will have noticed especially those items which most appeal to him, and will insensibly have made them the prominent features of the event, sometimes ignoring other points which were in reality much more important.
Now in the case of an observation on the mental plane this personal equation would not appreciably affect the impressions received, for since each would thoroughly grasp the entire subject it would be impossible for him to see its parts out of due proportion; but, except in the case of carefully trained and experienced persons, this factor does come into play in transferring the impressions to the lower planes. It is in the nature of things impossible that any account given down here of a vision or experience on the mental plane can be complete, since nine-tenths of what is seen and felt there could not be expressed by physical words at all; and, since all expression must therefore be partial, there is obviously some possibility of selection as to the part expressed. It is for this reason that in all our Theosophical investigations of recent years so much stress has been laid upon the constant checking and verifying of clairvoyant testimony, nothing which rests upon the vision of one person only having been allowed to appear in our later books.
But even when the possibility of error from this factor of personal equation has been reduced to a minimum by a careful system of counter-checking, there still remains the very serious difficulty which is inherent in the operation of bringing down impressions from a higher plane to a lower one. This is something analogous to the difficulty experienced by a painter in his endeavour to reproduce a three-dimensional landscape on a flat surface—that is, practically in two dimensions. Just as the artist needs long and careful training of eye and hand before he can produce a satisfactory representation of nature, so does the clairvoyant need long and careful training before he can describe accurately on a lower plane what he sees on a higher one; and the probability of getting an exact description from an untrained person is about equal to that of getting a perfectly-finished landscape from one who has never learnt how to draw.
It must be remembered, too, that the most perfect picture is in reality infinitely far from being a reproduction of the scene which it represents, for hardly a single line or angle in it can ever be the same as those in the object copied. It is simply a very ingenious attempt to make upon one only of our five senses, by means of lines and colours on a flat surface, an impression similar to that which would have been made if we had actually had before us the scene depicted. Except by a suggestion dependent entirely on our own previous experience, it can convey to us nothing of the roar of the sea, of the scent of the flowers, of the taste of the fruit, or of the softness or hardness of the surface drawn.
Of exactly similar nature, though far greater in degree, are the difficulties experienced by a clairvoyant in his attempt to describe upon the physical plane what he has seen upon the astral; and they are furthermore greatly enhanced by the fact that, instead of having merely to recall to the minds of his hearers conceptions with which they are already familiar, as the artist does when he paints men or animals, fields or trees, he has to endeavour by the very imperfect means at his disposal to suggest to them conceptions which in most cases are absolutely new to them.
Small wonder then that, however vivid and striking his descriptions may seem to his audience, he himself should constantly be impressed with their total inadequacy, and should feel that his best efforts have entirely failed to convey any idea of what he really sees. And we must remember that in the case of the report given down here of a record read on the mental plane, this difficult operation of transference from the higher to the lower has taken place not once but twice, since the memory has been brought through the intervening astral plane. Even in a case where the investigator has the advantage of having developed his mental faculties so that he has the use of them while awake in the physical body, he is still hampered by the absolute incapacity of physical language to express what he sees.
Try for a moment to realize fully what is called the fourth dimension, of which we said something in an earlier chapter. It is easy enough to think of our own three dimensions—to image in our minds the length, breadth and height of any object; and we see that each of these three dimensions is expressed by a line at right angles to both of the others. The idea of the fourth dimension is that it might be possible to draw a fourth line which shall be at right angles to all three of those already existing.
Now the ordinary mind cannot grasp this idea in the least, though some few who have made a special study of the subject have gradually come to be able to realize one or two very simple four-dimensional figures. Still, no words that they can use on this plane can bring any image of these figures before the minds of others, and if any reader who has not specially trained himself along that line will make the effort to visualize such a shape he will find it quite impossible. Now to express such a form clearly in physical words would be, in effect, to describe accurately a single object on the astral plane; but in examining the records on the mental plane we should have to face the additional difficulties of a fifth dimension! So that the impossibility of fully explaining these records will be obvious to even the most superficial observation.
