I will put it very simply. In May of 1921 God took me up into a high mountain of inspiration and intense ecstasy. A brilliant flash like lightning severed my bodily sensation from my consciousness and I found myself freed from my body and wholly in the Mind universe of Light, which is God.
And then God said to me, “Behold thou the unity of things in Light of Me, and the seeming separateness of all things in the two lights of my divided thinking. See thou that I, the Undivided, Unchanging One, am within all divided things, centering them, and I am without all changing things, controlling them.”
And the secrets of the universe were unfolded to me in their great simplicity as the doors to the Light opened fully to my consciousness. In less time than it takes to put it into words, I knew all there was to know of the CAUSE of all effect, for there was very little to know. In that hour it was as though the infinity of complexity within the moving kaleidoscope were suddenly taken apart and it was shown to me that the entirety of its illusion was but three mirrors and a few bits of broken glass. Likewise the universal kaleidoscope was but moving mirror waves of dual light extending from their equilibrium in God from Whom all creating things spring in octave electric waves just as ocean’s waves spring from the calm sea.

[Walter Russell] pioneered in foreseeing two of the greatest discoveries of modern times – the isotopes of hydrogen, which led to the discovery of heavy water, and the two new elements used in the atomic bomb. He announced the complexity of hydrogen to a body of distinguished scientists years before the truth of his statement was verified. But it is the atomic bomb that will prove to be the earth-shaking, epoch-making discovery of the future. The two newly discovered elements which formed the basis of the atomic bomb, called Neptunium and Plutonium, were published in his charts of the elements in 1926. He named them Uridium and Urium. He also predicted that if ever discovered the pressures of this planet would not be sufficient to hold them together.
“It is almost humorous to speak ‘guarding the secret, locking it up in American and British archives’”, was his comment. “Knowledge cannot be locked up. It is cosmic and wide open to every thinker, and limited only to his knowledge. And there is enough new knowledge right in this country today to make this present value of atomic secrecy worthless in a very few years.”
