`It is a cosmic law that what has once taken place can never vanish, but must reappear later in a metamorphosed form. Every thought, feeling and action brought about by man does not only affect the world around him but will re-appear in the future...' (From the Preface) This course of lectures was originally offered as private, strictly verbal instruction to a select group of esoteric pupils. In an atmosphere of earnest study, Rudolf Steiner `translated' from the Akashic Script valuable concepts of human and cosmic knowledge into words of earthly language - content that is often not to be found in his later lectures. Although working within the Theosophical Society, Steiner was an independent spiritual teacher: `... I would only bring forward the results of what I beheld in my own spiritual research.' The manifold, exact and detailed descriptions of the events of evolution in these lectures form a background to the evolving figure of the human being. The mighty event of the moon leaving the Earth, vividly described, took place - according to Rudolf Steiner - in order to provide an environment suited to human progress. The wonderful moment when the higher being of man descended in a bell-like form and enveloped the lower human body, still on a level with the animals, depicts what eventually provided human beings with a body suited to the development of the self or `I'. Spiritual beings and the great initiates led humanity along the path it was destined to tread. Rudolf Steiner presents a sweep of occult knowledge, including the phases of planetary evolution, various myths and symbols, human physical and spiritual organs, illness, reincarnation, and much more. Also included are unexpected insights into specific phenomena such as dinosaurs, bacteria, radiation, black and white magic, the Sphinx and Freemasonry.
