Rudolf Steiner approaches this spiritual-scientific task from two perspectives. In Kassel, Germany, he deepens insight into Theosophy and Rosicrucianism, showing their relationship to science and religion. Although presented as an "introduction," Steiner was never interested in simply providing information. His insights are fresh and with new illustrative examples. These lectures deepen and develop key elements found in his foundational written works. Also featured are the fascinating question-and-answer sessions from the Kassel lectures.
