“It will be seen at once that even in the study of inorganic matter a man gains immensely by the acquisition of this vision.  Not only does he see the astral part of the object at which he looks, which before was wholly hidden from him; not only does he see much more of its physical constitution than he did before, but even what was visible to him before is now seen much more clearly and truly. * * * Another strange power of which he may find himself in possession is that of magnifying at will the minutest physical or astral particle to any desired size, as through a microscope—­though no microscope ever made, or ever likely to be made, possesses even a thousandth part of this psychic magnifying power.  By its means the hypothetical molecule and atom postulated by science become visible and living realities to the occult student, and on this closer examination he finds them to be much more complex in their structure than the scientific man has yet realized them to be.  It also enables him to follow with the closest attention and the most lively interest all kinds of electrical, magnetic, and other etheric action; and when some of the specialists in these branches of science are able to develop the power to see these things whereof they write so facilely, some very wonderful and beautiful revelations may be expected.

“This is one of the SIDDIHIS or powers described in the Oriental books as accruing to the man who devotes himself to spiritual development, though the name under which it is there mentioned might not be immediately recognizable.  It is referred to as ’the power of making oneself large or small at will,’ and the reason of a description which appears so oddly to reverse the fact is that in reality the method by which this feat is performed is precisely that indicated in these ancient books.  It is by the use of temporary visual machinery of inconceivable minuteness that the world of the infinitely little is so clearly seen; and in the same way (or rather in the opposite way) it is by enormously increasing the size of the machinery used that it becomes possible to increase the breadth of one’s view—­in the physical sense as well as, let us hope, in the moral—­far beyond anything that science has ever dreamt of as possible for man.  So that the alteration in size is really in the vehicle of the student’s consciousness, and not in anything outside of himself; and the old Oriental books have, after all, put the case more accurately than have we.  I have indicated, though only in the roughest outlines, what a trained student, possessed of full astral vision, would see in the immensely wider world to which that vision introduced him; but I have said nothing of the stupendous change in his mental attitude which comes from the experimental certainty regarding matters of paramount importance.  The difference between even the profoundest intellectual conviction, and the precise knowledge gained by direct personal experience, must be felt in order to be appreciated.”
