His books remain in print, and the principles he taught as "Science of Mind" have inspired and influenced many generations of metaphysical students and teachers.
In addition to taking up a job with the city government, Holmes and his brother, a Congregationalist minister, studied the writings of Thomas Troward, Ralph Waldo Emerson, William Walker Atkinson, and Christian D.
[4] After leading small private meetings throughout the city, in 1916 Holmes was invited to speak at the Metaphysical Library in Los Angeles.
Subsequently, Holmes' lectures continued moving to ever-larger spaces, including the Biltmore Hotel, and the Wiltern Theatre, which seats more than 2800.
The primary teaching of New Thought is that physical form is created by a Universal Mind, or God, which manifests—or literally reflects—the dominant belief system of all living persons.
[11]Holmes argued that human beings have access to the power of this Universal Mind by directing their thoughts—in particular, their beliefs about the present or the future.
In his book, he described this as follows: Experience has taught us that the subjective tendency of this intelligent Law of creative force may consciously be directed and definitively used.
The proper kind of denial is based upon the recognition that, in reality, there is no limitation, for Mind can as easily make a planet as an acorn.
"[16] Holmes ultimately came to believe in a "core concept" – what he saw as a "Golden thread of truth" that ran through all of the world's religions as well as in science and philosophy.
The California College of Medicine, and the Foundation Academic University of Spiritual Understanding in Venice, Italy, awarded him a Doctor of Letters.
In 1942, he was bestowed with the Cross of the Commander of the Grand Humanitarian Prize of Belgium, and in 1944 he was named an honorary member of the Eugene Field Society.
