From the back of the book:
Homeopathy has always recognised that a disease is a physical manifestation of a central, but intangible disturbance of the Vital Force. Only by understanding the relationship between symptoms and the disturbance can we understand the disease. Mystic ideas such as the Cabbala and Swedenborgianism can be used to better understand the correspondence between a disease and its symptoms.
In this excellent book, Fraser has "quite brilliantly drawn together the threads of the higher realms of human experience and brought them down to earth to be of immense practical use in our everyday practices." (Janet Snowdon) He discusses a range of philophies, starting from Plato and working through a fascinating range, making relevant and insightful points throughout.
