This material universe, thus produced by the concentrated visions of all the souls entering into the eternal vision, is made up of all the physical bodies of all such souls, linked together by the medium of universal ether. But although the bodies which thus occupy different points of space are linked together by the universal ether, we are not permitted to find in this elemental ether, the medium which links the innumerable souls together. And we are not permitted this because in our original assumption such souls are themselves the half-creators, as well as the half-discoverers, of that universe whose empty spaces are thus filled. The material ether which links all bodies together cannot, since it is a portion of such an universe, be itself the medium from the midst of which these souls create that universe. But if, following our method of regarding every material substance in the world as the body of some sort of soul, we regard this universal ether as itself the body of an universal or elemental soul, then we are justified in finding in this elemental omnipresent soul diffused through space, the very medium we need; out of the midst of which all the souls which exist project their various universes. We are thus faced by a universe which is the half-creation and half-discovery of all living souls, a universe the truth and beauty of which depend upon the eternal vision, a universe whose material substance is entirely composed of the actual physical bodies of those very souls whose vision half-creates and half-discovers it. We thus reach our conclusion that there is nothing in the world except personality. The material universe is entirely made up of personal bodies united by the personal body of the elemental ether. What we name the universe, therefore, is an enormous group of bodies joined together by the body of the ether; such bodies being the physical expression of a corresponding group of innumerable souls joined together by the soul of the ether. In the portions of this book which deal with the creative energy of the soul I have constantly used the expression "objective mystery"; but in my concluding chapter I have rejected and eliminated this word as a mere step or stage in human thought which does not correspond to any final reality. When I use the term "objective mystery" I am referring to the original movement of the individual mind when it first stretches out to what is outside itself. What is outside itself consists in reality of nothing but an unfathomable group of bodies and souls joined together by the body and soul of the ether which fills space.
