This audiobook is the book Living Nonviolent Communication, by the same author, distilled into 4 lectures. The first book blew my mind when I read it a few years ago, completely changing my parenting and teaching and how I relate to other humans in general. This seemted as a handy reminder of those values and strategies, for me. I think it would also serve as a good introduction, for others who have not yet encountered Marshall Rosenberg's work.
