Part three of the Collected Works. Although A.E. was a poet, painter, newspaper editor, and political writer, it is as a mystic that he is best known today. His writings on the subject are of major importance to all who are interested in the unseen worlds. This contains all A.E.'s known writings on the subject: not only are the texts of The Candle of Vision, Song and Its Fountains, The Avatars, The Interpreters, and Imaginations and Reveries here, but so also are all his contributions to The Irish Theosophist and other esoteric journals, his introductions to and reviews of books, and the interview in W.Y. Evans Wentz's The Fairy Faith in Celtic Countries. Also included is The Return, a hitherto unpublished short work, together with an introductory note by Monk Gibbon.
