What might result from hearing a particular song, wearing used clothing, or witnessing an accident? Ethnographic accounts of the Navajo refer repeatedly to the influences of events on health and well-being, yet until now no attempt has been made to clarify the Navajo system of rules governing association and effect.

This book focuses on the complex interweaving of the cosmological, social, and bodily realms that Navajo people navigate in an effort alternately to control, contain, or harness the power manifested in various effects. Following the Navajo life-course from conception to puberty, Maureen Schwarz, professor emeritus of anthropology, explores the complex rules defining who or what can affect what or whom in specific circumstances as a means of determining what these effects tell us about the cultural construction of the human body and personhood for the Navajo.

Schwarz shows how oral history informs Navajo conceptions of the body and personhood, showing how these conceptions are central to an ongoing Navajo identity. She treats the vivid narratives of emergence life-origins as compressed metaphorical accounts, rather than as myth, and is thus able to derive from what individual Navajos say about the past their understandings of personhood in a worldview that is actually a viable philosophical system.

Working with Navajo religious practitioners, elders, and professional scholars, Schwarz has gained an unusually firm grasp of the Navajo highlighted by the foregrounding of Navajo voices through excerpts of interviews. These passages enliven the book and present Schwarz and her Navajo consultants as real, multifaceted human beings within the ethnographic context.
