Dr. Ernest Holmes and the Birth of New Thought

From time to time, we are blessed to know people of apparent genius, people whose insight, understanding, and love are influential in changing the thinking of whole generations, and whose impact will be felt for years to come. Dr. Ernest Holmes was such a person.

Dr. Ernest Holmes founded the spiritual movement that became United and International Centers for Spiritual Living. Born in 1887 on a small farm in Maine, Dr. Holmes spent his teenage years outdoors exploring such mysteries as “What is God? Who am I? Why am I here?” His inquiries led to his 1926 book, The Science of Mind, which outlines the foundational viewpoints of modern New Thought. Dr. Holmes is also the author of numerous other books on metaphysics and originated the Science of Mind magazine, which has been in continuous publication since 1927.​

The Science of Mind®: the Spiritual and Material Universe are One


The Science of Mind is the core teaching of Centers for Spiritual Living; it is a philosophy that integrates spiritual truths with science and physics. Simply put, the Science of Mind teaches the unity of all life. Intentions and ideas flow through a field of consciousness, which actually affect and create the world around us. This idea is common to most major religions and is supported by the teachings of psychology and quantum physics.

In the Science of Mind, we believe that the secret to living a successful life is to consciously choose positive and productive thoughts. Put another way, “As you think, so you become.”

Our Philosophy

About Science of Mind

Our Founder

It is the intention of Centers for Spiritual Living to use Science of Mind principles as a force for good in our world by transforming personal lives.

In the Science of Mind, we believe that the fields of religion and science are complementary, and that science will prove what the mystics have said for thousands of years about the nature of God, human beings, and the Universe. These beliefs are being proven even now by many quantum physicists who have found that the universe is made up of energy that cannot be destroyed and is infinitely intelligent.

The Sierra Center for Spiritual Living is a spiritual community and way of life that honors all paths to God. We provide spiritual tools for personal transformation, and it is our intention to help make the world a better place.

As an Open and Affirming Community, we extend a warm welcome to all people in search of a spiritual community where they are respected and accepted for who they are - we strive to inspire and support each and every person in growing into their highest potential. A Center for Spiritual Living is a place to make friends, share experiences with like-minded people, and know the power and presence of God in your daily life.

What We Believe - Our Guiding Principles

Sierra Center for Spiritual Living is an affiliated member of Centers for Spiritual Living, a global organization with hundreds of "centers" for spiritual living.

We believe that the Universe is fundamentally spiritual, and that it has intelligence, purpose, beauty and order. Our beliefs are in harmony with the basic tenets of all the world's great religions and for that reason we honor all paths to God. Whether we call it God, Spirit, Energy, or Universal Intelligence, every person, place and thing emanates from this spiritual universe. We believe this Universal Intelligence is within us, as well as around us, and that we are conscious of it.

We believe that God is a loving intelligence, operating in and through all life, never separate from anyone or anything. Through classes, study, and spiritual practice we come to understand our oneness with this indwelling Divine Presence. We teach and practice a way of life where we can all learn how to live in accordance with spiritual principles.  We call these principles the Science of Mind.

Centers for Spiritual Living support the positive transformation of both our personal lives and the world itself.



At Sierra Center for Spiritual Living, we teach people how to have a personal relationship with God. When we are deeply connected with Spirit, other areas of our lives fall into place — we can do more for others, be better stewards of the Earth, and bring more peace and harmony to the world.

What We Believe – Our Guiding Principles

We believe that the universe is spiritual and has intelligence, purpose, beauty, and order. Our beliefs are in harmony with all the world’s great spiritual teachings, and we honor all paths to God. Whether we call it God, Spirit, Energy, or Universal Intelligence, we are ever conscious that all people, places, and things emanate from this Universal Intelligence that is within us and all around us.

You and God are Inseparable

We believe that God is a Loving Intelligence, operating in and through all life, never separate from anyone or anything. Through study and spiritual practice we come to understand our oneness with this indwelling Divine Presence. We teach and practice a way of life where we can all learn how to live in accordance with spiritual principles. These principles, which we call the Science of Mind, are as reliable as the laws of physical science. We believe in Cause and Effect and teach that “It is done unto you as you believe.” In essence, your thinking and your expectations create your reality. By studying and applying spiritual laws, you can change your unconscious beliefs and create improved conditions in your life.

Be a Part of an Inclusive Community

Sierra Center for Spiritual Living teaches a New Thought philosophy that incorporates affirmative prayer, meditation, healing, visioning, and other spiritual tools to help you lead a spiritual life, think positively, and love deeply. As a member of our community, you’ll find the spiritual tools to transform your personal life and make the world a more peaceful, harmonious, and prosperous place.

The New Thought tradition dates to the 1880s and has its roots in the Transcendentalist Movement of the 1830s. New Thought has an enduring and respected legacy that includes luminaries such as Ralph Waldo Emerson, Emma Curtis Hopkins, Phineas Quimby, and Walt Whitman. Some of the better known authors today whose writings represent our teachings are Michael Bernard Beckwith, Deepak Chopra, Wayne Dyer, Byron Katie, Caroline Reynolds, and Eckhart Tolle, as well as many others.

Our teachings incorporate the ancient wisdom of all the spiritual traditions through the ages. People of all spiritual paths - Christian, Jewish, Buddhist, Hindu, Muslim, New Age and others - are welcome in our community.​
