This book is a good starting point among the hundreds of books written by Rudolf Steiner. He sees a tripartate model of the individual here: body, soul and spirit, cautioning us that these are only approximate terms. This book will give a description of some of the regions of the supersensible world. The reader who is willing to admit the existence of the sensible world only will regard this delineation as a mere unreal production of the imagination. He, however, who looks for paths that lead beyond this world of the senses will soon learn to understand that human life only gains in worth and significance through sight into another world. Such a man will not, as many fear, be estranged from the "real" world through this new power of vision. He learns to know the causes of life, while without it he gropes like a blind man through their effects. Only through the understanding of the supersensible does the sensible "real" acquire meaning.
This masterwork of the esoteric places humankind at the very heart of the vast, invisible processes of cosmic evolution. Esoteric science is the science of what takes place esoterically, in the sense that it is perceived not outside in nature but where one's soul turns when it directs its inner being toward the spirit. Rudolf Steiner worked on rosicrucian cosmology for many years to make it increasingly precise and accurate. This work remains the most effective presentation to date of a spiritual alternative to contemporary materialist cosmologies and of human evolution. Readers learn how the creation and evolution of humanity is embedded at the heart of the vast, invisible web of interacting cosmic beings, through whom the alchemical processes of cosmic evolution unfold. A detailed, practical guide to the methods or exercises, including the Rose Cross Meditation," through which such initiation knowledge can be attained.
