Insomnia, anxiety, depression, digestive, cardiac, or respiratory disorders... Many of these ailments do not originate within us, but are invisible legacies passed down from our family history. They are often passed down silently, like echoes of trauma. They are fragments of the emotional history of our parents, grandparents, and ancestors; experiences that, without our knowledge, leave a deep mark on our physical health and inner balance. Sometimes these symptoms do not appear by chance; they arise on significant dates or at ages that repeat the cycles of the family tree, guided by the hidden pulse of our genealogical clock. After twenty-five years of research, Élisabeth Horowitz demonstrates that intimate events and family secrets span generations and shape our bodies -- and their metabolism -- from the very moment of conception. Some genealogical configurations, marked by repetitions and similarities, can even modify our DNA. It seems impossible, and yet where could such transformations arise if not from the family fabric that sustains us? This revelation completely transforms our idea of inheritance. Horowitz invites us to explore this legacy and embark on a path to liberation: to recognize who symbolically inhabits our bodies, to detect the family wounds that still manifest themselves in us, and, with the help of the concrete tools offered in this exciting book, to restore harmony and open ourselves to profound healing.
