This article examines early colonial Kaqchikel Maya notions of the self, souls, and the heart. By integrating ethnohistorical data and contemporary ethnographic observations, we show that Kaqchikeles viewed the self as contingent on a dynamic balance of cosmic forces acting on the individual. The ways in which these forces are seen to effect one's state of being are documented through an extensive discussion of Kaqchikel metaphors of the heart and soul. We conclude by noting the importance of understanding processes of continuity (as well as change) in cultural constructions and argue for the continued utility of such approaches in ethnohistorical research.
