The Science of Mind is the study of Life and the nature of the laws of thought in a spiritual Universe. This philosophy believes there is One Infinite Mind that includes all there is, whether it be human intelligence or the invisible Presence of God, and is built upon the premise that we are living in a spiritual universe whose sole government is one of harmony where the use of right ideas is the enforcement of its law.

In 1927, a teacher, writer, and lecturer by the name of Ernest Holmes defined and established the Science of Mind philosophy by uncovering a clear and simple method he discovered while researching the wisdom of the ages from many disciplines. This newfound practical and spiritual approach to living an abundant life evolved into what is now the Science of Mind Textbook, which has been the cornerstone to Religious Science churches and Centers for Spiritual Living around the world.

Over the course of his life, the textbook became a beacon of light to millions of readers and followers, but to others, the 600+ page tom presented itself as an obstacle to beginners simply because of its intimidating size. In what turned out to be one of his last books before his death in 1960, Holmes published this introduction after its initial release as an article in the Science of Mind Magazine to help individuals easily understand the concepts before taking the first steps of their new spiritual journey.
