The Ancient Wisdom is a book by Annie Besant published in 1897, as per the dedication in the leader of the undated first pressing. In this book, Besant introduces and explains the Physical plane, Astral plane, Mental plane and other planes of existence. George Farthing has criticized the book, because Besant has introduced new terms like "Etheric body" into the theosophical literature, which were not used by Blavatsky or the theosophical Mahatmas.
