Twin Roads to the New Millennium:: The Christmas Conference and the Karma of the Anthroposophical SocietyFirst published in the run up to the new millennium, van Manen's seminal study remains a unique and important source for understanding the spiritual and karmic background to the Anthroposophical Movement and Society, as founded around the work of the twentieth century seer and scientist Rudolf Steiner.
