A "must" for the serious student of Russell science and philosophy, The Universal One is Walter Russell's first expression of his new Cosmogony explaining the Mind-centered electromagnetic universe. Russell later revised some of the content of The Universal One in The Secret of Light and A New Concept of the Universe. Students of the Russell science should be aware of the historic sequence of Walter Russell's books of science, and note the various changes in details which Walter Russell himself made. Nikola Tesla told Walter Russell to hide his cosmogony from the world for a thousand years. Though a century or more ahead of its time, The Universal One, uniting spiritual Cause and scientifically observable Effect in a seamless whole, is now appealing to the many people-scientists and laymen alike-who are examining the nature of science and consciousness. In this 1926 historic volume, Walter Russell first reveals the possibility of transmutation of the elements. This is a universe of Mind, a finite universe, limited as to cause, and to the effect of cause. A finite universe, in which the effects of cause are limited, must also be limited as to cause; so when that measurable cause is known, then can man comprehend and measure all effects. The effects of cause are complex and mystify man, but cause itself is simple. The universe is a multiplicity of changing effects of but One unchanging cause. All things are universal. Nothing is which is not universal. Nothing is of itself alone. Man and Mind and all creating things are universal. No man can say: 'I alone am I.' There is but One universe, One Mind, One force, One substance. When man knows this in measurable exactness then will he have no limitations within those which are universal." - Walter Russell, from The Prelude to The Universal One.
