Excerpt: ...But there are other problems to be explained, problems of life and mind, and the same knowledge you have explains them as well as the others, if you simply avail yourself of it. That you do not consider the atom as four-fold instead of two-fold is your own fault. I have not told you anything you did not already know. I have only asked you to apply your present knowledge of physics to these problems of life and mind, and apply your reasoning powers. "The chording vibration in an atom of matter of "The two planes produces Force, or phenomena "The three planes produces Life-the silver chord "The four planes produces Mind-the golden chord. "You say there is no gulf between the prakritic and etheric worlds; that it is one continuous world; and all its phenomena are by continuity and not impact. That is true, but it is not the whole truth. "There is no gulf to cross between the prakritic and etheric worlds; none to cross between that and the manasic. The four worlds are one great world, continuous, interchangeable. Through the four as well as through the two, there is continuity and not impact. Whether it is an atom or a world, the four are there. Nothing, no combination of atoms, no matter of any kind, however small or large, can exist in this prakritic world unless it has the four elements, which from time immemorial our philosophers have called Earth, Water, Fire, Air, meaning the four globes or forms of matter in the universe. We do not have to leave the earth to live in the etheric globe. It is here. Nor do we have to go millions of miles to reach the pranic globe. It is here. The problems of light and heat are no easier than the problems of birth and death. The pranic globe is within us; within everything. So is the manasic. "It is here on these higher planes that the chances for worthy study are greatest. At least we think so, though you may not. We live on the manasic-pranic-etheric globe on precisely the same terms that we live on this of...
