<![CDATA[Abstract: This study examines the implementation of Tri Kaya Parisudha (purifying thought, speech, action)-based learning, its impact on student character formation, and its relevance for character education. Using qualitative-descriptive methods (participatory observation, interviews, documentation), supported by constructivist, social cognitive, and positive reinforcement theories, findings reveal that systematic habituation, teacher exemplification, and curricular integration of spiritual-moral values enhanced students' ethical awareness, fostering disciplined conduct, orderliness, politeness, time management, and environmental care. Tri Kaya Parisudha is established as an effective, context-sensitive character education methodology, particularly relevant in Hindu-based schools, offering a sustainable pedagogical framework.
