In the Universe, Earth, Human Being lectures, Rudiolf Steiner gives a vast panoramic view of the evolution of the world, humanity and the kingdoms of nature. We see the activities of the higher spiritual hierarchies and their involvement in our creation and development, the development of the world through the Lemurian, Atlantean and our own post-Atlantean period; the growth of humanity into an individualized ego-being; the relationship between the post-Atlantean cultural periods - and specifically between the ancient Egyptian/Chaldean/Judaic and our own; and much more.
