I have been a long time fan of Norman Fischer. When I don't even know what questions I have but feel confused, I turn to his writing to help settle me and this book is now my favorite.
In this book, he explains the role of imagination and how it relates to growth on the spiritual path. I wouldn't typically call Zen a very imaginative practice but Fischer helps me to see it in a way I never imagined. (pun intended). It's the sign of a great teacher who can take a fundamental tenant and make you see it in an entirely different light.
I personally like his emphasis on using this as a form of inspiration as that's what this book gave me. Hope and inspiration can drive a person to make leaps where otherwise they would have faltered: this book serves as a much-needed springboard for practitioners navigating the path.

An enlightened read, always interesting, and a different perspective. Good writer and topic from an expert in the field.
