Book excerpt: From best-selling author and spiritual teacher Wayne W. Dyer comes My Greatest Teacher, which follows a man's journey to find understanding and reconciliation with his past. Despite having a loving family and a fulfilling career as a university professor, Ryan Kilgore has always held deep resentment and anger toward the father who abandoned him when he was born. When these emotions take their toll on his marriage-and his relationship with his own son-Ryan realizes he must confront these unhealed wounds in order to move forward in his life. While at an academic conference, he embarks on a search to track down his father, Big Bob. Along the way, Ryan encounters friends and acquaintances of Big Bob, while reawakening memories of his childhood. My Greatest Teacher is an inspiring tale of how we can transform suffering and pain into forgiveness and love, and the lessons we can learn through the most difficult challenges we face.
