This paper explores how the spiral structure transforms the dualistic and hierarchical boundary and contributes to promote understanding and reconciliation in the poetry of Joy Harjo(1951- ). Spiral structure is a concept that shows the influence of the indigenous American belief in the inherent spirituality within all life forms. Unlike the hierarchical structure, a pyramid where God, human beings and other life forms are clearly classified, the spiral structure is an image where all beings resonate. In “Autobiography” Green Corn dance evokes forgiveness in the speaker`s mind. In “Fury of Rain” and “Nine Lives” the whirling circle of storm energizes the poet with aspiration to transform into a perfect being. In “Eagle Poem” the circle of an eagle`s motion brings the viewer into the elevated state of being sacred. Through the spiral structure Harjo seeks to diminish barriers that separate humans from the natural world, thereby to return to a non-dualistic world and eventually to reconcile the alienated beings. “Transformations” expresses the indigenous American belief about interconnectedness of this world into next by mentioning a story about the dying old man. “Reconciliation,” is about a radical redefinition of a god, who extends into a mother, a father, and a lover. “The Dawn Appears with Butterflies” and “The Place the Musician Became a Bear” show how people continue their presence in the sacred circle of being. Through her poems Harjo is successfully suggesting a way of seeing our own lives in a new light. Transformation and a spiraled world structure eventually contribute in bringing mutual understanding and reconciliation.
