Sacred sexuality has been an important if neglected feature of Western eroticism from the century down to the present day. Founded in Romania, the Movement for Spiritual Integration into the Absolute (MISA) turned sacred esotericism into the central feature of a mass movement, which now counts 30,000 members worldwide. Based on extensive fieldwork and interviews, the book explores the history of MISA from its origins through to the COVID-19 pandemic, exploring its ideas around Tantra and sexuality. It also discusses MISA’s approach to visual arts and cinema, including its early intervention into the slippery world of adult movies. The study concludes with a look at hostile reactions to MISA, which have led to the issuing of arrest warrants against its founder amid a series of criminal accusations.
