In ancient times humanity possessed an innate knowledge of the spiritual foundations of existence. Such knowledge could be acquired through inwardly accompanying the cycle of the year and its connected great seasonal festivals. But this instinctive knowledge had to be lost in order for human beings to discover individual freedom. In our time, as Sergei O. Prokofieff demonstrates in this comprehensive work, \'...this knowledge must be found anew through the free, light-filled consciousness of the fully developed human personality\'. Tracing the spiritual path of the yearly cycle, Prokofieff penetrates to the deeper esoteric realities of the seven Christian festivals of Michaelmas, Christmas, Epiphany, Easter, Ascension, Whitsun and St John\'s Tide. Basing his research on the work of the twentieth-century initiate Rudolf Steiner, he reveals how these festivals are spiritual facts that exist independently of religious traditions and cultural customs. Working with the festivals in an esoteric sense can provide a true path of initiation, ultimately enabling an experience of the Being of the Earth, Christ. The journey of study through this book can thus lead the reader to an experience of the modern Christian-Rosicrucian path, along which \'...it is possible to take the first steps towards life in partnership with the course of cosmic existence\'.
