Michaela Glockler speaks on themes relating to the esoteric path of spiritual development and its therapeutic task for the individual and community. Giving an account of the evolution of the ancient mysteries in relation to medicine, she discusses the application of inner work in outer action, reflecting on modern social and ethical issues such as organ transplantation and the termination of pregnancy. The author addresses primarily those in the healing professions, but this book will be of interest to anyone concerned with the new science of the spirit.
