This book is focused on the leading edge of spiritual science, developed, outlined, and published by the discoverer and founder of Christian Science, Mary Baker Eddy, between 1866 and 1910. The book contains critical aspects of her work, including her seal from 1881, under which her works were published until 1908, which itself stands as metaphor for the scientific foundation that she was working on. The presentation in the book begins with her illustrated poem, Christ and Christmas that provides essential metaphoric references. The references are designed to enrich the understanding in society of her works -works that are scientifically founded on the biblical "city foursquare," which she referred to as the "city of our God." The book presents a number on interrelated leading-edge elements of spiritual science that were developed, outlined, and published by her over the span of 44 years. It contains numerous rarely-known aspects that are critical for an understanding of all that she has accomplished, and for what needs yet to be accomplished to heal humanity, advance civilization, prevent wars, even nuclear war, and prepare the world for the start of the next Ice Age in 30 years. The scientific aspects that are drawn together in this book, by researcher Rolf A. F. Witzsche, based on decades of research, bring to light amazing scientific-spiritual aspects that have a great healing potential. The book is published by Cygni Communications Ltd, in Canada (http: //www.ice-age-ahead-iaa.ca/)
