This article brings together various textual materials relating to the worship of Prajñāpāramitā in mediaeval Monsoon Asia. In particular, it covers sources from South Asia, mainland Southeast Asia (Angkor), maritime Southeast Asia (Java and Bali), and Southern China (Yunnan). The aims of this critical survey are twofold. On the one hand, the article argues for the importance of ritual language within wider discussions on cultural and linguistic cosmopolitanism within and beyond the so-called ‘Sanskrit Cosmopolis’. These discussions have too often focused on royal epigraphic eulogies, neglecting religious literature. On the other hand, it highlights the key role of Prajñāpāramitā as a protective deity, and the transregional heritage of her invocatory texts. These texts strike one for their traditional choice of imagery and associations, thus reminding of the importance of exoteric traditions within the history of Southeast Asian Buddhism.
