The Cycle of the Year as Breathing-Process of the Earth (Lectures Section)

These lectures focus on the four Christian festival seasons, elaborating on the complementary nature of Christmas with Midsummer and Easter with Michaelmas. The esoteric realities behind the festivals are discussed in relation to sub-earthly and super-earthly powers, the equinoxes, the ancient Mysteries, Michael’s activity, morality, and the musical-poetic and visual arts. This volume along with Michaelmas and the Soul-Forces of Man completes the entire German volume GA 223.

Life Between Death and Rebirth (Lectures Section)

In these lectures Rudolf Steiner deals with the experience of the human soul during and after death. He describes the states of consciousness experienced by our deceased loved ones and how we, taking into account their new consciousness, can communicate with them and even help them. Reading these descriptions, it becomes clear that excarnated souls need the spiritual support of those presently incarnated, and that those still on earth in turn derive enlightenment and support from their former earth companions.

Materialism and the Task of Anthroposophy (Lectures Section)

In this history of the development of human consciousness, Steiner makes the startling announcement that the world has already ended in the fourth century A.D. Since then we have been living in an increasingly spiritual world on a disintegrating, dying earth. We have simply been asleep to this spiritual reality around us.
