A great many passages in this book testify to Charles Fillmore's persistent interest in what is popularly called atomic energy and the promise held out by its development of a better world for mankind. As he rejoiced in the scientific achievement of its discovery so he tirelessly devoted his thought to its guidance into the channels of peaceful use. On every occasion he urged those having to do with its development to make sure that this unique form of energy, this great gift of the Father, would not be used to worsen life and destroy mankind.

From another standpoint Charles Fillmore's mind was simply fascinated by the idea of the atom, this infinitesimal particle of substance, and the enormous energy locked up in it. At times he thought of it as the most perfect representation in the manifest world of that divine mental or spiritual energy which pervades all things and which, when properly expressed through the minds of His children, serves so greatly to glorify God. At other times he thought of it as the very essence of this mental or spiritual energy, Spirit-mind itself! The reader will find each one of these standpoints set forth over and over--perhaps vaguely and mystically at times--but ever testifying to the alertness and vitality of Charles Fillmore's mind and his unflagging interest in everything in his world.
