This article reviews the principal tendencies in the contemporary studies of indigenous South American religious traditions. It divides the field into studies of socioreligious formations (particularistic and universalistic formations, more specifically) and studies of cosmologies or worldviews (so-called perspectivism). It then discusses two recent, pioneering biographies of South American shamans which, more than any other in the field, offer original approaches to understanding shamanic historical consciousness, cosmopolitics, the constant struggles of shamanic spirits to sustain the cosmos against sorcery spirits that threaten to undermine the cosmic order.
