I was asked that question recently. Despite having read many books during my 70 years—not including all those reads as background and research for my own recently published book—one title skyrocketed to the top of my brain.
I read Women Who Run with the Wolves: Myths and Stories of the Wild Woman Archetype by Clarissa Pinkola Estes in 1993, the year after its publication. This book sparked two Wild Woman poems and a large mixed media art piece.
More recently, I was reintroduced to Wolf. Known as Grand Teacher, Wolf, as spirit animal, walks a sacred path, gathering ways of wisdom and sharing that new knowledge with others. This describes the whole of my life: teaching, speaking, and writing to heal and inspire, to share what I have learned. The Courage to Care: Being Fully Present with the Dying is my latest sharing. Perhaps it will transform your life or that of someone you hold dear.
