These esoteric lectures examine the underlying laws inherent in reincarnation and karma. In 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 processes which are the basis of the other phenomena of world existence..." This volume includes, the difference between "moon karma" and "sun karma", the influences of Christian and Mohammedan thinking, the transformation of inner human qualities from one life to the next, and more.
