We receive from our ancestors much more than a material inheritance. Without being aware of it, we are beneficiaries or victims of a psychogenerational legacy, with its positive and negative aspects, which will mark our lives. Not only will we bear many mistakes, we will also repeat them on occasion. The concept of «transgenerational» designates the vital process of transmission of attitudes, psychic contents and family secrets throughout several generations. This new human science, heir to psychoanalysis, identifies the psychological traces that our ancestors have left on us, in order to understand our behavior and our life. This book is the result of seven years of research with leading therapists who use psychogenealogy in their work.
