This collection of essays by leading scholars explores the present, dynamic state of metaphysical religion in America. It includes chapters that: put survey data on this growing group in context, clarify definitional issues in the study of spirituality in general and metaphysical spirituality in particular, and assess the networks, conferences, rituals, festivals, retreat centers and periodicals recently developed by metaphysicals. The contributors discuss characteristic practices of mental healing and meditation, and show the reach of metaphysical ideas into public spaces and popular media cultures. One particular chapter also addresses the growing controversy over the legitimacy of metaphysical individuals and movements that appropriate elements of Native American and Asian religious beliefs and practices to enrich or sustain their own practice. This rich collection appeals to students, researchers, professionals and the layperson interested in knowing more about the history and more importantly the direction that American metaphysical religion is taking.
