Creator's Description: The myth of the Chinese princess Kong jo's geomantic divination of Tibet prior to the founding of the Central Temple of Lhasa (Lha sa gtsug lag khang) – and in particular the striking image of the land of Tibet as a "supine demoness" – has been the object of considerable academic comment. Generally, it has been read as a metaphor either of monastic Buddhism's misogynist tendencies, or of its superposition over putative religious precursors. In this article, the difficulties that attend these interpretations of the supine demoness image are assessed when examined within the context of the princess's wider divination, as presented in Tibetan mythic histories such as the Ma ni bka' 'bum, The Clear Mirror of Royal Genealogy, and the Pillar Testament (Bka' chems ka khol ma), and in particular when it is viewed within the context of the Valley's actual topographic structure. In light of these, it is proposed that both the supine demoness image and the other elements of Kong jo's divination should be understood as it has always been presented by Tibetan sources – as part of an established tradition of Chinese geomancy, a tradition which has itself been re-organized as a medium for Buddhist themes of liberation.
