With the founding of the General Anthroposophical Society at Christmas 1923/24, Rudolf Steiner provides an impulse for the renewal of the mystery tradition. This impulse is prepared over three seven-year periods, during which Rudolf Steiner systematically renews each of the three pre-Christian types of mysteries. In the first phase, he revitalizes the 'Mysteries of Light' from Greece through the spiritualization of thought; in the second, he rejuvenates the 'Mysteries of Space' from Egypt through the enlivening of the artistic impulse; and in the third phase, he renews the northern mysteries, the 'Mysteries of the Earth,' in order to reintegrate our civilizational and economic problems into the realm of the spiritual and meaningful. Only against this background can one understand what a renewed mystery tradition could be today and what our tasks are in this context.
