Purpose: The purpose of this paper is to illustrate and discuss the application of mindfulness practices rooted in Buddhism as the methodological praxis in implementing participatory action research (PAR) projects with older Thai adults. Design/methodology/approach: The paper draws on the researchers' reflexive accounts of participatory action conducted with older Thai participants in a series of four PAR projects in the five senior schools located in the northern, southern, northeastern and central regions of Thailand. Findings: The paper demonstrates the translation of Buddhist mindfulness into a PAR methodological approach and shares actual practices of mindfulness in each stage of the research process. Originality/value: This paper provides practical implications for researchers to incorporate the mindfulness methodology to unlock presuppositions and attachments to pre-existing PAR frameworks and open new ways of knowing that emerge out of the lived experience at the present contextual moment.
