liquid form. There is still rarer matter than air, called ether, that science declares exists, although it cannot condense it, nor in any way whatever grasp, measure or contact it. How, then, is it known to exist? Because certain phenomena could not be, without it. Just as we could not have sound without the air through which it travels, neither can we have electrical phenomena without the ether as it's medium through which to work. So in air and ether we have two kinds of invisible matter, and in electricity we have a force working through one of them whose visible results we see daily. This is as far as physical science is at present able to go into the unseen, in this direction, but occult science goes much further. Its methods are as definite and exact as those of physical science, but it's facts are obtained through the development of certain faculties or senses latent in all human beings, that give those who possess them an advantage over those who have but the five senses, much like a person with those five senses would have over another who had the four, but did not process the sense of sight. What has thus been learned of the invisible side of nature constitutes some of the truths philosophy offers to the world.
Theosophy divides the universe into seven planes or regions of nature, but for our present purpose we need give attention to but three of them: the physical, astral and mental. On these occur all the phenomena of life and death, and a clear understanding of them will dispel all doubt and drive away all fear for either our friends or ourselves. Now, while two of these divisions of the universe are invisible to physical sight and impalpable to physical touch, they are, nevertheless, composed of matter, and the first thing we should get clearly in mind is that this invisible matter interpenetrate's and completely permeates all visible matter. If we could take a large
