Followers of the early "New Age" movement known as New Thought, which was wildly popular at the turn of the 20th century, were intensely interested in gleaning the fruit of all of humanity's spiritual wisdom. In this 1908 work, one of the most influential New Thought writers and editors shares with Western readers the "root-ideas" of Indian language, symbology, and philosophy that have given birth to much of the knowledge of all of humanity, casting the mysteries of the East in an easily comprehensive light. He discusses: . the Sankhya system . the Vedanta system . Patanjali's yoga system . Buddhism . Sufiism . the Vedas . and more. 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, some of which are likely still unknown today, including "Yogi Ramacharaka" and "Theron Q. Dumont."
