As he says in the 2004 preface to his book,
"...while much has changed, in other ways much is still the same. We human beings still struggle with almost exactly the same personal, interpersonal, spiritual, and community issues that we were struggling with over 3,300 years ago when the Ahseret Hadibrot, the ten words or commandments, were received at the foot of Mount Sinai."
The inner cover of Felder's book bears these words, and they are worth repeating:
"Some of the issues addressed in this book can stir up intense feelings and memories. Anyone who has a history of psychiatric disorder, feels emotionally unstable, is taking tranquilizers, or is on antianxiety or antidepressant medication should not do the exercises in this book without first consulting a qualified mental health professional."
