Fire in the Head: Shamanism and the Celtic Spirit,by Tom Cowan.
A remarkable exploration of shamanism using cross-cultural myths to explain the history and roots of the Celtic spirit. Cowan presents the traditional fantastic experiences of the shaman in an amazingly perceivable framework. His depiction of archetypes in well-known myths and legends opens one to the ability to read all things symbolically, thus, as the dynamic spiritual presences that they are. His telling of olde tales connects their spirit with a modern audience.
