In this article, we introduce the ContERN special issue on ethnographies of the esoteric. While the study of esotericism has been dominated by historical-philological scholarship, recent years have seen an increase in anthropological approaches to contemporary esotericism.

We address these questions using examples from the articles in the present special issue as well as other recent ethnographies of esoteric subject matter
