In our everyday lives, we are constantly challenged by the phenomenon of evil in all its many manifestations. But how can we cope with this seemingly eternal hindrance? In the first of these three essays, Sergei Prokofieff suggests that we start by developing a knowledge of the forces of evil in order to learn how they work in human evolution. Such knowledge is, in itself, the beginning of the process of overcoming evil. In order that members of the Anthroposophical Society might go further along this path, Rudolf Steiner gave them the spiritual 'Foundation Stone of the Good'. This Foundation Stone - which consists of light, imaginative form, and the substance of love - can live in our hearts and souls as a firm foundation for esoteric work, and a creative contribution towards the overcoming of evil. Ultimately it can lead us to a conscious experience of Christ in the etheric realm of the earth. In the second and third essays, Prokofieff examines further themes relating to the etheric advent of Christ, and its connection with the Foundation Stone of the Good.
