The Ancient Wisdom is a book by Annie Besant published in 1897 that seeks to provide comprehensive and educational explanations of the global theosophical teachings and their relationships to one another. Introducing such topics as the Physical plane, Astral plane, Mental plane, and other planes of existence, this remarkably insightful text is the perfect example Besant's marvellous ability to express challenging spiritual ideas in an engaging and accessible manner, which she does here in a clear order and with smooth language. Annie Besant was a prominent British socialist, theosophist, activist for woman's rights, writer and supporter of Irish and Indian self-rule. Originally published in 1897, we are proud to republish this scarce classic with an original biography of its author.
