Without material objects Space is unthinkable

Let us start with ourselves, and try to imagine a million million miles, and then multiply them by another million million miles, a million million times. What have we done? Simply extended our mental yard-stick a certain number of times to an imaginary point in the Nothingness that we call Space. So far so good, but the mind intuitively recognizes that beyond that imaginary point at the end of the last yard-stick, there is a capacity for an infinite extension of yard-sticks–an infinite capacity for such extension. Extension of what? Space? No! Yard-sticks! Objects! Things! Without material objects Space is unthinkable.
It has no existence outside of our consciousness of Things. There is no such thing as Real Space. Space is merely an infinite capacity for extending objects. Space itself is merely a name for Nothingness. If you can form an idea of an object swept out of existence, and nothing to take its place, that Nothing would be called Space, the term implying the possibility of placing something there without displacing anything else.
Size, of course, is but another form of speaking of Distance. And in this connection let us not forget that just as one may think of Space being infinite in the direction of largeness, so may we think of it as being infinite in the sense of smallness. No matter how small may be an object thought of, we are still able to think of it as being capable of subdivision, and so on infinitely. There is no limit in this direction either. As Jakob has said: “The conception of the infinitely minute is as little capable of being grasped by us, as is that of the infinitely great. Despite this, the admission of the reality of the infinitude, both in the direction of greatness and of minuteness, is inevitable.”
And, as Radenhausen has said: “The idea of Space is only an unavoidable illusion of our Consciousness, or of our finite nature, and does not exist outside of ourselves; the universe is infinitely small and infinitely great.”
The telescope has opened to us ideas of magnificent vastness and greatness, and the perfected microscope has opened to us a world of magnificent smallness and minuteness. The latter has shown us that a drop of water is a world of minute living forms who live, eat, fight, reproduce, and die. The mind is capable of imagining a universe occupying no more space than one million-millionth of the tiniest speck visible under the strongest microscope–and then imagining such a universe containing millions of suns and worlds similar to our own, and inhabited by living forms akin to ours–living, thinking men and women, identical in every respect to ourselves. Indeed, as some philosophers have said, if our Universe were suddenly reduced to such a size–the relative proportions of everything being preserved, of course–then we would not be conscious of any change, and life would go on the same, and we would be of the same importance to ourselves and to the Absolute as we are this moment. And the same would be true were the Universe suddenly enlarged a million-million times. These changes would make no difference in reality. Compared with each other, the tiniest speck and the largest sun are practically the same size when viewed from the Absolute.
We have dwelt upon these things so that you would be able to better realize the relativity of Space and Time, and perceive that they are merely symbols of Things used by the mind in dealing with finite objects, and have no place in reality. When this is realized, then the idea of Infinity in Time and Space is more readily grasped.
As Radenhausen says: “Beyond the range of human reason there is neither Space nor Time; they are arbitrary conceptions of man, at which he has arrived by the comparison and arrangement of different impressions which he has received from the outside world. The conception of Space arises from the sequence of the various forms which fill Space, by which the external world appears to the individual man. The conception of Time arises from the sequence of the various forms which change in space (motion), by which the external world acts on the individual man, and so on. But externally to ourselves, the distinction between repletion of Space and mutation of Space does not exist, for each is in constant transmutation, whatever is is filling and changing at the same time–nothing is at a standstill,” and to quote Ruckert: “The world has neither beginning nor end, in space nor in time. Everywhere is center and turning-point, and in a moment is eternity.”
Next, the Intellect informs us that we must think of the Absolute as containing within Itself all the Power there is, because there can be no other source or reservoir of Power, and there can be no Power outside of the All-Power. There can be no Power outside of the Absolute to limit, confine, or conflict with It. Any laws of the Universe must have been imposed by It, for there is no other law-giver, and every manifestation of Energy, Force, or Power, perceived or evident in Nature must be a part of the Power of the Absolute working along lines laid down by it. In the Third Lesson, which will be entitled The Will-to-Live, we shall see this Power manifesting along the lines of Life as we know it.
Next, the Intellect informs us that it is compelled to think of the Absolute as containing within Itself all possible Knowledge or Wisdom, because there can be no Knowledge or Wisdom outside of It, and therefore all the Wisdom and Knowledge possible must be within It. We see Mind, Wisdom, and Knowledge manifested by relative forms of Life, and such must emanate from the Absolute in accordance with certain laws laid down by It, for otherwise there would be no such wisdom, etc., for there is nowhere outside of the All from whence it could come. The effect cannot be greater than the cause. If there is anything unknown to the Absolute, then it will never be known to finite minds. So, therefore, ALL KNOWLEDGE that Is, Has Been, or Can Be, must be NOW vested in the One–the Absolute.
This does not mean that the Absolute thinks, in any such sense as does Man. The Absolute must Know, without Thinking. It does not have to gather Knowledge by the process of Thinking, as does Man–such an Idea would be ridiculous, for from whence could the Knowledge come outside of itself. When man thinks he draws to himself Knowledge from the Universal source by the action of the Mind, but the Absolute has only itself to draw on. So we cannot imagine the Absolute compelled to Think as we do.
But, lest we be misunderstood regarding this phase of the subject, we may say here that the highest occult teachings inform us that the Absolute does manifest a quality somewhat akin to what we would call constructive thought, and that such “thoughts” manifest into objectivity and manifestation, and become Creation. Created Things, according to the Occult teachings are “Thoughts of God.” Do not let this idea disturb you, and cause you to feel that you are nothing, because you have been called into being by a Thought of the Infinite One. Even a Thought of that One would be intensely real in the relative world–actually Real to all except the Absolute itself–and even the Absolute knows that the Real part of its Creations must be a part of itself manifested through its thought, for the Thought of the Infinite must be Real, and a part of Itself, for it cannot be anything else, and to call it Nothing is merely to juggle with words. The faintest Thought of the Infinite One would be far more real than anything man could create–as solid as the mountain–as hard as steel–as durable as the diamond–for, verily, even these are emanations of the Mind of the Infinite, and are things of but a day, while the higher Thoughts–the soul of Man–contains within itself a spark from the Divine Flame itself–the Spirit of the Infinite. But these things will appear in their own place, as we proceed with this series. We have merely given you a little food for thought at this point, in connection with the Mind of the Absolute.
So you see, good friends and students, that the Intellect in its highest efforts, informs us that it finds itself compelled to report that the One–the Absolute–That which it is compelled to admit really exists–must be a One possessed of a nature so far transcending human experience that the human mind finds itself without the proper concepts, symbols, and words with which to think of It. But none the less, the Intellect finds itself bound by its own laws to postulate the existence of such an One.
