This paper is based on research conducted during my ongoing collaboration as a participant-observer with the Cuyamungue Institute (CI) of New Mexico, a self-identified nonreligious organization that uses postures to help participants achieve ecstatic trance experiences via a ritual process that prominently features sonic support of trance by the sound of a rattle or drum. While the purpose of the practice—which the Institute has referred to in such terms as “Ecstatic Trance Postures (ETP)” and “Ritual Body Postures”—is ostensibly spiritual in nature, apparent benefits for physical and emotional health have been reported by participants and observed in empirical studies carried out in collaboration with the CI. With appropriate nuance, the Institute traditionally emphasizes the ways these benefits demonstrate the process’s spiritual efficacy more than how they are outcomes desirable on their own merit. As I have continued to work with the CI, the discourse has gradually shifted. At present, the leadership of the Institute give more consideration than before to emotional health benefits as specific goals of the practice, yet spiritual conceptions maintain a dominant presence in conversations and achieving a deep connection with the “alternate reality / spirit realm / unbounded universe” remains the primary objective.
