Subconscious and the Superconscious Planes of Mind, written by W.W. Atkinson in 1909, is a somewhat supernatural text on the different levels at which the mind works and functions. There are the sub-conscious (below normal), conscious (normal), and super-conscious (above normal) levels, which Atkinson describes in detail. He also covers the elements of each level-for example, in the subconscious our memory works and resides. While based in hard facts, Atkinson uses the mind theories to justify instances such as telepathy and mind reading, in which he strongly believed.

American writer WILLIAM WALKER ATKINSON (1862-1932) was editor of the popular magazine New Thought from 1901 to 1905, and editor of the journal Advanced Thought from 1916 to 1919. He authored dozens of New Thought books under numerous pseudonyms, including "Yogi," some of which are likely still unknown today.
