In 16 concise chapters, Rudolf Steiner reveals how we can look through the material veil of this world and glimpse the world of the spirit. With meditation and concentrated thought we can develop our intuition and clairvoyance and even our powers of ESP. Written "to be of use to those who are really in earnest in seeking knowledge of the spiritual world," this book continues to inspire today. Austrian scholar, philosopher and spiritual researcher RUDOLF STEINER (1861-1925) has written dozens of books, including Philosophy of Freedom, Theosophy, An Outline of Occult Science, and Knowledge of the Higher Worlds.
