Now, about this element in which we live. It undoubtedly has a place in space, for it is all around the earth. Yes, every tree visible has its invisible counterpart. When you, before sleep, come out consciously into this world,[1] you see things that exist, or have existed, in the material world also. You cannot see anything in this world which has not a physical counterpart in the other. There are, of course, thought-pictures, imaginary pictures; but to see imaginatively is not to see on the astral plane--not by any means. The things you see before going to sleep have real existence, and by changing your rate of vibration you come out into this world--or rather you go back into it, for you have to go in, in order to come out. Imagination has great power. If you make a picture in the mind, the vibrations of the body may adjust to it if the will is directed that way, as in thoughts of health or sickness. It might be well as an experiment, when you want to come out here, to choose a certain symbol and hold it before your eyes. I do not say that it would help to change the vibration, but it might. I wonder if you could see me if just before falling asleep you should come out here with that thought and that desire dominant in your mind? I am strong to-day, because I have been long with one who is stronger; and if you want to make the experiment of trying to find me this night, I may be able to help you better than at another time. There is so much to say, and I can seldom talk with you. If you were differently situated and quite free from other things, I could perhaps come often. I am learning much that I should like to give you. For instance, I think I can show you how to come out here at will, as the Masters do constantly. At first I took only your arm to write with, but now I get a better hold of the psychic organisation. I saw that I was not working in the best way, that there was a waste somewhere, so I asked the Teacher for instruction in the matter. By this new method you will not feel so tired afterwards, nor shall I. I am going now, and will try to meet you in a few minutes. If the experiment should fail, do not be discouraged; but try again some other time. You will know me all right, if you do see me.
