The Khmer Rouge period had a hugely negative impact on the knowledge and practices of Khmer divination. At present, Khmer divination and astrology has been revitalized with many forms of it being embedded in people’s everyday lives in both rural and urban settings, such as in the capital Phnom Penh. With the re-emergence of numerological fortune-telling, Khmer practitioners are now turning to Thai numerological books, such as ‘Patithin Neung Roi Pee (100-year calendar)’, ‘Tamra Phromachati’, and ‘Tamra Plu Luang’ to supplement the diminished body of traditional Khmer knowledge that survived the war. This paper aims to explore how Cambodia divinatory and astrologicalauthority have been revitalized and reinvented through that of their Thai counterparts within the flows of globalization and modernity.
