In family constellations work begins in one's soul and family. If reconciliation has been achieved it can be extended to other groups and contexts, what is what leads to peace and reconciliation with one's soul? Personal development and growth are possible when we include all those previously excluded. Before we can admit, however, there is a conflict. Peace and reconciliation arise only after conflict. In his new book, Bert Hellinger investigates the emotional prerequisites that are necessary for reconciliation. The author finds an answer and examples in historical conflicts between people and cultures. But Hellinger also focuses on complex peace among religions, for example between Christianity and Islam, as well as between conquerors and conquered in America, or masters and slaves in the United States.
