It's a good move to treat this topic from a FAQ, Q and A format. Dr. Engle, referred to as Dr. Dan, anticipates most of the questions that will come for anyone considering this strain of psychotherapy. It's like a practical version of a Michael Pollan book on psychedelics. I listened to this book, and in many sections the dialog works well. But in others, particularly our narrator, Alex, in conversation with his therapist, Dr. Kate and his Pa and Granny Jane, are laughable. Still it functions as a decent download of information on its subject.
