- This edition is unique; - The translation is completely original and was carried out for the Ale. Mar. SAS; - All rights reserved. The purpose of this book is to give a description of certain parts of the supersensible world. Those who wish to admit only the sensible world will consider such a description a vacuous product of the imagination. But those who wish to seek the paths that lead out of the world of the senses will soon come to understand that human life only acquires value and meaning if they penetrate with their gaze into another world. This penetration does not distract man, as many fear, from 'real' life. For only by this path does he learn to stand firm and secure in life. He learns to know its causes, while, if he ignores them, he gropes like a blind man through the effects. Only through knowledge of the supersensible world does sensible 'reality' acquire meaning. Therefore, this knowledge enhances, not diminishes, our capacity for life. Only he who understands life can become a truly 'practical' man. The author of this book does not describe anything that he cannot testify to from his own experience, from the kind of experience that can be had in this field. He will therefore only expound things that, in this sense, he has experienced himself. The way we read in our times does not apply to this book. In a certain sense, every page, often even a few sentences, must be conquered with effort. This is what he consciously strives for. For only in this way can the book become for the reader what it has to be for him. He who merely skims through it, will not have read it at all. The truths it contains must be experienced. The science of the spirit is only effective in this sense.
