Theosophy is a key work for anyone seeking a solid grounding in spiritual reality as described by Rudolf Steiner. The book is organized in four parts. First, Steiner builds up a comprehensive understanding of human nature, beginning with the physical bodily nature and moving up through the soul nature to our spiritual being: the I and the higher spiritual aspects of our being.This then leads to the experience of the human being as a sevenfold interpenetrated being of body, soul, and spirit. In the next section Steiner gives an extraordinary overview of the laws of reincarnation and the workings of karma as we pass from one life to the next. This prepares us for the third section where Steiner shows the different ways in which we live, during this life on earth and after death, in the three worlds of body, soul, and spirit, as well as the ways in which these worlds in turn live into us.Finally, a succinct description is given of the path of knowledge by which each one of us can begin to understand the marvelous and harmonious complexity of the psycho-spiritual worlds in their fullness.
