Fire in the Head is Tom Cowan's engrossing, intelligent, and shamanically well-informed work that is an important gift to all those Westerners seeking a knowledge of Celtic shamanism. In The Song of Wandering Aengus , William Butler Yeats refers to the '"fire in the head" that characterizes the visionary experience. Tom Cowan has pursued this theme in Fire in the Head , a lyrical cross-cultural exploration of shamanism and the Celtic imagination that examines the myths and tales of the ancient Celtic poets and storytellers, and outlines techniques used to access the shaman's world.
