In his lectures on karma, given in 1924, Steiner spoke of the principal Aristotelian and Platonic traditions and the movements based on their thinking. Van Manen studies the streams of destiny connected to those streams and elaborates on Steiner’s presentations, while tackling the seeming contradictions in the Karmic Relationships lecture series. - The author discusses the background to these groupings of destiny, beginning with the cosmic Michael School in the life before birth. He throws light on many different esoteric aspects connected to Anthroposophy, including the archetypal representations of thinking arising from the Middle Ages; the Arthurian and Grail movements; the mystery of "Old" and "Young" souls; the individuals identified as "Seekers for Christ" and "Servants of Michael," as well as the "Shepherds" and "Kings." - We are led to the point where the two principal groups of souls incarnate and come together on Earth for the first time ever—an event that will take place within the contemporary anthroposophic movement. In an inspiring conclusion, the author presents his thoughts on a great Pentecostal event at the end of the twentieth century and expounds on the tasks of the new millennium and the future of Anthroposophy.
