11 lectures, various cities, January-May, 1909 (CW 109)These talks reveal a particular aspect of how humankind have been guided spiritually throughout history--by the life forces and astral bodies of the great initiates and avatars that were preserved, duplicated, and interwoven with the leading personalities of history.Steiner gives numerous examples of this process, but he says that such inspired people are rare today.Nevertheless, we have the possibility of elevating ourselves in the future to the point where we can receive into ourselves the "I-being" of the Christ, which is indeed our greatest goal--"not I but Christ in me."Contents: * The Principle of Spiritual Economy in Connection with Questions of Reincarnation * Christianity in Human Evolution, Leading Individualities, and Avatar Beings * More Intimate Aspects of Reincarnation * Results of Spiritual Scientific Investigations of the Evolution of Humanity * On the Occasion of the Dedication of the Francis of Assisi Branch * The Macrocosmic and Microcosmic Fire: The Spiritualization of Breath and Blood * The Event of Golgotha -- The Brotherhood of the Holy Grail * Ancient Revelations and Learning: How to Ask Modern Questions * The God of the Alpha and the God of the Omega * From Buddha to Christ
