Scholarly studies of magic, sorcery, and witchcraft have differed in their conclusions about the empirical efficacy of such practices and the persistence of related concepts. Often marginalized in these accounts, however, are local commentaries that address those same issues. Drawing on two years of ethnographic research in the highland Jambi region of central Sumatra, this article examines magical practices found in the region, the modes through which they are acquired, and connections to a set of ethereal beings that lie at the source of those supernatural abilities. While the belief in and practice of magical powers remain widespread, there exists a general 'discourse of decline'. This article analyzes several elements of that discourse, particularly declining potency, practice, relevance, and believability, showing where local perspectives converge and diverge with those that underlie alternative scholarly frameworks.
