The nineteenth century witnessed a proliferation of alternative religious currents and practices, appropriating earlier traditions, entangling geographically distinct spiritual discourses, and crafting a repository of mindscapes eminently suitable to be accommodated by later generations of thinkers and practitioners. Penned by specialists in the field, this volume examines important themes and figures pertaining to this occult amalgam and its resonance into the twentieth century and beyond. Global guises of the occult, ranging from the Americas and Europe to India, are variously addressed, with special attention to the crucial role of mesmerism and the origins of modern yoga.
