If you are wondering what is meant by the word soul, this book will help you. According to the introduction by Thomas Moore, James Hillman is "an artist of psychology", that is, he regards the psyche as fundamentally poetic. Hillman reccomends that we pay attention to inner images and is able to show how they relate to the symbols found in different cultures. The distinction between soul and spirit, which most people do not seem to make, is clarified in terms of images. Spirit is sulphuric and up in the peaks, soul is salty and down in the valleys.
There is some more practical wisdom here too, I have found the essay on betrayal particularly helpful. I found this book to be a challenge, both to my understanding and to my assumptions.
