Gerald May, a senior fellow in contemplative theology and psychology, wrote this as he was terminally ill. I am not deeply religious in the traditional sense and this book was not written from that perspective. It is not a story of a wilderness journey as others are but a different perspective on what "wilderness" is to each of us and the benefit to be gained from getting in touch with "it" and ourselves.
Here is a bit from the inside cover "the natural world has a power to inspire the best and soothe the worst in each of us. It also has much to teach us about the wilderness within and the divine presence that is manifest in nature.
Probably not a book for everyone but I enjoyed the perspective.
