"Knowledge Of the Higher Worlds And Its Attainment" was originally published in 1938. This inspiring book by Rudolf Steiner offers a wealth of knowledge on the path of esoteric initiation. Included is much information on the higher body, higher planes of existence, and the spiritual encounter with the 'Guardians of the Threshold', as well as basic information on the mystical belief system. This book would be an excellent addition to the bookshelf of anyone with an interest in the subject. Contents Include: How is Knowledge of the Higher World Attained?; The Stages of Initiation; Some Practical Aspects; The Conditions of Esoteric Training; Some Results of Initiation; The Transformation of Dream Life; The Continuity of Consciousness; The Partition of Human Personality During Spiritual Training; The Guardian of the Threshold; The Great or Second Guardian of the Threshold. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new biography of the author.
