The Panacea Society was a small religious community of women that was established in England in the early twentieth century. They followed the early nineteenth-century mystic Joanna Southcott, as well other emerging spiritual movements of the day, and developed a remarkable spiritual healing practice that spread around the world. Based on the thousands of letters held in the Society’s healing archive, which were sent by ordinary people from around the world, Alastair Lockhart offers a detailed study of the religious ideas of religious seekers from the 1920s to the 1970s. Focusing on Great Britain, Finland, Jamaica, and the US, Lockhart provides unique insight into the personal nature of spirituality in recent times and how ancient and modern spiritual strands were harnessed to the needs of late-modern spiritual seekers. This book addresses debates about the complexity and meaning of the rise or decline of religion in the twentieth century and the processes involved in the formation of popular nontraditional spiritualities. It informs our understanding of global and transnational religions and recent forms of spiritual healing.
