My ability to prove God as a scientific fact and bring Him within the range of mans comprehension through incontrovertible evidence of His controlling Presence in all creating things is the result of having fully experienced that rarest of all spiritual phenomena known as the Illumination into the Light of Cosmic Consciousness, during a thirty-nine day and night period in May and June of 1921.
I will not describe that phenomenon here, for it will be fully described in the following pages, except to say that the seat of sensation becomes completely severed from its centering conscious Mind for intervals, followed by intervals of complete severance, one becomes wholly Mind, the One Mind of God, in which exists all-knowledge, all-power, and all-presence. Relatively few such experiences of illumination have been recorded throughout world history.
Naturally, the entirety of the secrets of Creation were mine to know as a complete and consistent cosmogony, which knowing enabled me to envision the universe as a whole. Underlying the creative process of the universe was a fundamental principle of such simplicity that I felt that I could gather the great scientists of the world together and give them that entire principle of such simplicity that I felt that I could gather the great scientists of the world together and give them that entire principle in a few minutes, for I had been aware that for decades science has been searching for such an underlying principle, which would apply to all phenomena.
