THEO. Not at all, for we see with our naked eye planets and even stars at immeasurably greater distances; but it is owing to those six globes being outside our physical means of perception, or plane of being. It is not only that their material density, weight, or fabric are entirely different from those of our earth and the other known planets; but they are (to us) on an entirely different _layer_ of space, so to speak; a layer not to be perceived or felt by our physical senses. And when I say “layer,” please do not allow your fancy to suggest to you layers like strata or beds laid one over the other, for this would only lead to another absurd misconception. What I mean by “layer” is that plane of infinite space which by its nature cannot fall under our ordinary waking perceptions, whether mental or physical; but which exists in nature outside of our normal mentality or consciousness, outside of our three dimensional space, and outside of our division of time. Each of the seven fundamental planes (or layers) in space—of course as a whole, as the pure space of Locke’s definition, not as our finite space—has its own objectivity and subjectivity, its own space and time, its own consciousness and set of senses. But all this will be hardly comprehensible to one trained in the modern ways of thought. ENQ. What do you mean by a different set of senses? Is there anything on our human plane that you could bring as an illustration of what you say, just to give a clearer idea of what you may mean by this variety of senses, spaces, and respective perceptions? THEO. None; except, perhaps, that which for Science would be rather a handy peg on which to hang a counter-argument. We have a different set of senses in dream-life, have we not? We feel, talk, hear, see, taste and function in general on a different plane; the change of state of our consciousness being evidenced by the fact that a series of acts and events embracing years, as we think, pass ideally through our mind in one instant. Well, that extreme rapidity of our mental operations in dreams, and the perfect naturalness, for the time being, of all the other functions, show us that we are on quite another plane. Our philosophy teaches us that, as there are seven fundamental forces in nature, and seven planes of being, so there are seven states of consciousness in which man can live, think, remember and have his being. To enumerate these here is impossible, and for this one has to turn to the study of Eastern metaphysics. But in these two states—the waking and the dreaming—every ordinary mortal, from a learned philosopher down to a poor untutored savage, has a good proof that such states differ.
