Lou Savary and Patricia Byrne have provided a valuable contribution in this book by clearly explaining Teilhard's doctrine of love on every level of life, from God to friendship, marriage, parenting, and human community. Their book is less a scholarly exposition on a Teilhardian doctrine of love than a masterful illumination of love as the core energy of evolving life. Each chapter clearly explains Teilhard's insights and then provides practical ways of incorporating these ideas into daily life.
