Query: A unique and informative book on the subject; enlightening

This is a thought-provoking book which stands apart from all others dealing with Celtic shamanism. Cowan offers detailed analyses on many different aspects of the Celtic brand of mysticism; he clears up the "clowdiness" that is often present when dealing with this complex system of symbology and myth. A wealth of subjects are covered, from the traces of shamanistic practice we find in the lives of Celtic heroes to the deeper significance of the Arthuran legends. The most interesting part of the book for me was the section on the Sacred Wound, a vital but mysterious part of shamanic initiation. This witty, energetic exploration of the Celtic mystical experience is definitely a must have for all interested in this genre.
