The Radha Tantra is a late (17th century) Shakta Tantra from Bengal. In this talk, we introduce this little-known but fascinating text as an example of how the transgressive side of Tantra can take the form of apologetics. Using Vaishnava sources, the Radha Tantra completely recasts the story of Radha and Krishna in a way that for Vaishnavas could be bewildering and infuriating, but that has much to say about the religious landscape of 17th-century Bengal.
