8 lectures, Oslo, Nov-Dec, 1921 (CW 79) The lectures in this book were delivered by Steiner in 1921. Today, their content remains valid and the world situation even more desperate and in need of change in keeping with spiritual-scientific knowledge. The need for developing "consciousness of the self as the spiritual essence of the free, individualistic, single-personality human being" is one of Steiner's unique contributions to the evolving history of humankind. This book marks another milestone on that path. This book is a translation of Die Wirklichkeit der hohren Welten ("The Reality of the Higher Worlds").
