In this revised and expanded edition of his classic debut, Sergei O. Prokofieff investigates the deepest mysteries of Rudolf Steiner’s life and individuality, from ‘the years of apprenticeship’ and ‘the great Sun period’ to ‘the path of the Teacher of Humanity’ and ‘the birth of the New Mysteries’. He discusses the earthly and supersensible aspects of the first Goetheanum, the implications of the Christmas Conference of 1923-24, and the Foundation Stone meditation that Steiner left as a legacy to members of the Anthroposophical Society.In his very personal Introduction, Prokofieff describes, in moving detail, the events in his life which led to his discovery of anthroposophy whilst living in Communist Russia, and how eventually he came to write this extraordinary study of Rudolf Steiner. The resulting volume - a work of secondary anthroposophical literature unprecedented in its depth and significance - was first published in Germany in 1982, meeting with equal amounts of acclaim, astonishment and controversy. It is published in this paperback edition to mark the 35th anniversary of the original publication.
