Christian D. Larson was a "New Thought" leader and teacher, as well as a prolific author of metaphysical and 'New Thought' books. He is credited by Horatio Dresser as being a founder in the New Thought movement. Many of Larson's books remain in print today, nearly 100 years after they were first published, and his writings influenced notable 'New Thought' authors and leaders, including 'Religious Science' founder, Ernest Holmes. In this title Larson attempts to apply the principle of faith in the realization of perfect health. He believed that "When the mind is in the truth it reflects only what is in the truth; the body will thus be filled, through and through, with perfect health; the personal man will express the strength, the life and the purity of the real man, and all that is beautiful and ideal in the within will manifest itself more and more in the without.".-Print ed.
