This is a metaphysical Christian essay from the New Thought tradition, written by Charles Fillmore, co-founder of the Unity Church. Its central argument is that the human body is literally the temple of God — that biblical structures like the Tabernacle and Solomon's Temple are allegories for the human mind and body as the dwelling place of the divine "I AM" or supermind. Fillmore contends that thought has measurable physical power: positive, spiritually-directed thinking fills the body with light and energy, while complaint and negativity cloud the mind and halt spiritual progress, mirroring how the Israelites halted when a cloud covered the Tabernacle. He invokes contemporary neuroscience — claims that scientists have measured the force of mental beams radiating from the brain — to validate biblical accounts of Moses's shining face and Pentecostal fire as literal descriptions of electromagnetic thought-energy. A distinctive recurring claim is that religion and science are not opposed but unified at the level of "Spirit-mind," with each failing when it ignores the other: religion by treating divine law as negotiable through prayer, and science by denying intelligence in evolutionary forces. The essay's practical thrust is that anyone can dissolve depression and poverty by consciously invoking "Christ" as a thought-force, treating Jesus's promises as both literally and spiritually operative.
