What is Science of Mind (SOM)?

Science of Mind® (also referred to as Religious Science) is the core teaching of Centers for Spiritual Living. Science of Mind is a philosophy that integrates spiritual truths with science and physics. Simply put, Science of Mind teaches the unity of all life. Intentions and ideas flow through a field of consciousness, which actually affects and creates the world around us. This idea is common to most major religions and is supported by the teachings of psychology and quantum physics. In Science of Mind, we believe that the secret to living a successful life is to consciously choose positive and productive thoughts.

Are Science of Mind and Religious Science the same?

Religious Science is the name of the church that Dr. Ernest Holmes started, which was the precursor to Centers for Spiritual Living. Dr. Holmes’ comprehensive book of teachings is entitled The Science of Mind. Members of Centers for Spiritual Living often use the phrases Science of Mind and Religious Science interchangeably.

Who was Ernest Holmes?

Dr. Ernest Holmes founded the spiritual movement that started Centers for Spiritual Living. Born in 1887 on a small Maine farm, Dr. Holmes spent his teenage years outdoors, asking himself “What is God? Who am I? Why am I here?” This questioning led to his 1926 book, The Science of Mind, which outlined the foundational viewpoints of modern New Thought. To learn more about The Life of Ernest Holmes enjoy this very enlightening and comprehensive article on Dr. Holmes on the Archives’ website.

What is an Archives?

Archives contain what is called Primary Source Material–original documents, records, manuscripts, photos, artifacts (objects such as furniture or personal belongings). These items are truly irreplaceable. This is why it is important to have proper archival quality storage systems to prevent deterioration of items (especially photos and film). This is also why it is important for an archive to scan and digitize as much of the material as possible so it can be preserved electronically and available forever.

Where is the SOM Archives located and can I visit?

The physical archives are located in the Centers for Spiritual Living Home Office at 573 Park Point Drive, Golden, Colorado 80401.

For a virtual or in person, tour, schedule an appointment with Executive Director Rev. Kathy Mastroianni at 720-496-1361 or Please allow one hour to explore all the amazing and sacred treasures available at the Archives. Tours are currently free and Love Offering donations are welcomed to support the work of the Archives.

NOTE:  As of March 11, 2024, the Archives is in the process of revealing a new location due to the Home Office selling the building, so please reach out before planning your visit.

What is the SOM Archives’ history?

In the late 1990’s, Rev. Drs. Marilyn and Richard Leo were invited to start collecting and organizing the history of Dr. Ernest Holmes and the Religious Science Movement, especially because Dr. Marilyn was a close family friend and neighbor of the Holmes. Dr. Richard made his transition in 2001 and Dr. Marilyn continued to lead this important project. In 2007, the Science of Mind Archives and Library Foundation became an official 501 (c) (3) nonprofit organization. In 2008, the Archives were moved to Encinitas, California, at the Holmes Institute Campus. In 2010 the Archives moved from Burbank, California to its current beautiful 2,600 square foot space shared by Centers for Spiritual Living Home Office in Golden, California.

What is the relationship between Centers for Spiritual Living (CSL) Home Office and the SOM Archives?

The SOM Archives is a separate 501 (c) (3) nonprofit organization housed in CSL’s Home Office and responsible for its own operations and fundraising.
