sadly, Edith Eger passed away this week. To honour her we have decided to re-release our episode because we think that there are important lessons to be learned about how to live one's life well from Edith.

Holocaust survivor Edith Eger shares her emotional journey of surviving Auschwitz, her encounter with Josef Mengele, and how she became known as the 'Ballerina of Auschwitz.' Edith highlights the slow, evolving process of coming to terms with her past, influenced by Viktor Frankl's work, and how she uses her traumatic experiences to help others as a psychologist, transforming trauma into a source of strength, healing, and forgiveness.
