Working with one's own biography is one of the most valuable tools in the field of potential development and personal growth. From birth to death, we unconsciously follow a rhythm. This knowledge dates back to ancient Greece and is enriched in this book by Martina and Michael with new insights from psychology, brain research, and their own work. The result is a book that describes the life phases and their significance for each individual in an understandable way. We all go through different life phases with changing qualities and energies. Each life phase presents us with specific tasks that help us grow and develop. By examining our past while considering the influences of the respective life periods, we gain a holistic view of our entire life. This automatically leads to a deep understanding of ourselves and our history. We recognize the common thread in our biography, allowing us to clearly grasp and utilize our potentials and possibilities. Thus, we see the meaning behind it and are able to reshape our lives.
