This eBook edition of "The Subconscious & The Superconscious Planes of Mind" has been formatted to the highest digital standards and adjusted for readability on all devices. Extract: "The great problems of modern psychology are found to consist largely of the phenomena of the mental operations and activities on planes other than those of ordinary consciousness. While the terminology of the subject is still in a state of transition, nevertheless certain terms have sprung into common use and are employed tentatively by those who write and teach of these wonderful regions of the mind." William Walker Atkinson (1862-1932) was a prolific writer. His works treat themes related to the mental world, occultism, divination, psychic reality, and mankind's nature. They constitute a basis for what Atkinson called "New Psychology" or "New Thought".
