William Walker Atkinson (1862–1932) was a prolific writer, attorney, merchant, and publisher, who is regarded as one of the pioneers of the New Thought movement—a movement that promoted the idea that the mind has the power to heal and to attract success and happiness. Atkinson's journey into the world of esoteric wisdom and the cultivation of the mind began after suffering a mental and physical breakdown, which led him to seek healing through non-traditional means. He discovered the principles of New Thought and, subsequently, experienced a remarkable recovery, which profoundly influenced his literary career. Atkinson wrote under several pseudonyms, including Theron Q. Dumont and Yogi Ramacharaka, producing an extensive body of work that delved into topics such as yoga, occultism, personal power, and success. Among his significant contributions is 'The Inner Secret' which encapsulates his exploration into the potential of the human mind and the realization of personal power through self-knowledge and mental discipline. Atkinson's legacy extends to the realm of mental science and the law of attraction, concepts he articulated with clarity and vigor. His works are marked by a didactic style aimed at elevating the individual through practical wisdom and mastery of the self. Atkinson's influence continues to resonate with readers interested in the application of mental forces and the achievement of personal potential.
