It is, however, from the field of science that the greatest help will come. The fact of the soul will eventually be proved through the study of light and of radiation and through a coming evolution in particles of light. Through this imminent development we shall find ourselves seeing more and penetrating deeper into that which we see today. One of the recognized facts in the realm of natural science has been the cyclic change in the fauna and flora of our planet. Animals, plentiful and familiar many thousands of years ago, are now extinct, and by means of their bones we endeavor to reconstruct their forms. Flowers and trees that once covered the surface of our planet have now entirely disappeared and only their fossilized remains are left to indicate to us a vegetation vastly different to that which we now enjoy. Man himself has changed so much that we find it difficult to recognize homo sapiens in the early primitive races of the far distant past. This mutability and obliteration of earlier types is due to a major factor among many. The quality of the light which promotes and nurtures growth, vitality and fertility in the kingdoms of nature has changed several times during the ages, and as it has changed it has produced corresponding mutations in the phenomenal world. From the standpoint of the esotericist, all [102] forms of life on our planet are affected by three types of light substance, and at the present time a fourth type is gradually making its presence felt. These types of light are:

1. The light of the sun.
2. The light in the planet itself - not the reflected light of the sun but its own inherent radiance.
3. A light seeping in (if I may use such a phrase) from the astral plane, a steady and gradual penetration of the "astral light" and its fusion with the other two types of radiance.
4. A light which is beginning to merge itself with the other three types and which comes from that state of matter which we call the mental plane - a light in its turn reflected from the realm of the soul.

An intensification of the light is going on all the time, and this increase in intensity began on the earth at about the time when man discovered the uses of electricity, which discovery was a direct result of this intensification. The electrification of the planet through the widespread use of electricity is one of the things which is inaugurating the new age, and which will aid in bringing about the revelation of the presence of the soul. Before long this intensification will become so great that it will materially assist in the rending of the veil which separates the astral plane from the physical plane; the dividing etheric web will shortly be dissipated, and this will permit a more rapid inflow of the third aspect of light. The light from the astral plane (a starry radiance) and the light of the planet itself will be more closely blended, and the result upon humanity and upon the three other kingdoms in nature cannot be over-emphasized. It will, for one thing, profoundly affect the human eye and make the present sporadic etheric vision a universal asset. It will bring within the radius of our range of [103] contact the infrared and ultraviolet gamut of colors, and we shall see what at present is hidden. All this will tend to destroy the platform upon which the materialists stand, and to pave the way, first, for the admission of the soul as a sound hypothesis, and secondly, for the demonstration of its existence. We only need more light, in the esoteric sense, in order to see the soul, and that light will shortly be available and we shall understand the meaning of the words, "And in Thy light shall we see light."

There is an aspect of human consciousness which has for [104] long baffled the materialistic psychologist, and this is the curious power of prevision, the ability to foresee and foretell with accuracy events coming in the immediate future, or distant happenings. There are warnings given by some inner monitor which have again and again saved man from death and disaster; there are the appearances, to their friends and relatives, of men or women who have just died, before any word of their death has been received. This is not in the field of telepathic knowledge of the death, but involves the appearance of the person. There is the power to participate in events in distant places and to recover the recollection of what transpired with accuracy as to place, personnel and detail. These powers and many similar previsions and recognitions have long bewildered investigators and must find correct explanation. In their wise investigation, in the accumulation of responsible evidence, and in the later substantiation of the prevision, it will begin to be seen that some factor exists in man which is not bound by space-time limitations, but which transcends the normal human consciousness. The present attempted investigation and explanations are inadequate and do not account satisfactorily for all the facts. When, however, they are approached from the standpoint of the soul, with its faculty of omniscience and its freedom from categories of past, present and future (for they are lost in the consciousness of the Eternal Now), we shall begin to understand the process a little more clearly. When the true Dweller in the body is recognized and the laws of prevision are discovered, and when the power to foresee is generally prevalent, then we shall begin to find ample proof of the existence of the soul. It will be impossible to account for the ordinary phenomena then current without admitting its existence.
