We may repeat ourselves, but at the same time we cannot emphasize it enough: This series of books, and with it this book, is not a general passing on information. Rather, it is aimed, consciously, at people who know that they need the content for themselves and their next task. People who have a certain high level of development, a certain high level of awareness and thus a certain high level of integrity. People who are able to receive information in a pure and clear manner and to deal with it with integrity.
