During 1924, before his last address in September, Rudolf Steiner gave over eighty lectures on the subject of karma to members of the Anthroposophical Society. These profoundly esoteric commentaries examine the underlying laws of reincarnation and karma, and explore in detail the incarnations of specific historical figures. In Rudolf Steiner's words, the study of karma is '...a matter of penetrating into the most profound mysteries of existence, for within the sphere of karma and the course it takes lie those processes which are the basis of the other phenomena of world existence...' In this eighth and final volume of the series, Rudolf Steiner offers insights on a variety of subjects, including Cosmic Christianity, the Michael impulse, the Arthur and Grail streams of wisdom, as well as the individualities of Gregory VII, Haeckel, Swedenborg, Loyola, Haroun al Raschid, Byron, Voltaire and others.
