Of all the myriad aspects of Indian learning to be incorporated into Tibetan Buddhist scholarship, one of the least likely would seem to be the Indian science of sensual pleasure, kāmaśāstra. Even so, we do find traces of Sanskrit kāmaśāstra transposed into Tibetan Buddhist idiom. The most innovative example is the Treatise on Passion (’Dod pa'i bstan bcos) written by Ju Mipam Jamyang Namgyel Gyatso (1846–1912). This article investigates the reasons why the polymath monastic scholar Ju Mipam included kāmaśāstra in his expansive literary output, as well as his sources and influences for doing so. It argues that Mipam's work builds on an intertextuality already apparent in late medieval Sanskrit tantric and kāmaśāstric works, but one that took on new importance in the context of the non-biased outlook (Tib. ris med) that characterized Ju Mipam's nineteenth-century eastern Tibetan milieu.
