The present study examines the relationship between spiritual intelligence and financial well-being among university teachers, with a particular focus on the mediating role of mindfulness. In the context of increasing financial complexity, understanding the psychological determinants of financial well-being has become essential. A purposive sample of 250 university teaching faculty members from Rajasthan was selected based on specific inclusion criteria, including age, income, and work experience. Standardized instruments were used to measure spiritual intelligence, mindfulness, and financial well-being. Data were analysed using correlation, regression, and mediation analyses through SPSS and PROCESS Macro (Model 4). The findings revealed that spiritual intelligence significantly and positively predicts financial well-being and mindfulness. Additionally, mindfulness was found to be a significant predictor of financial well-being. Mediation analysis further demonstrated that mindfulness partially mediates the relationship between spiritual intelligence and financial well-being. These results highlight the importance of internal psychological resources in shaping financial outcomes. The study contributes to the existing literature by providing an integrated framework linking spiritual intelligence, mindfulness, and financial well-being, and suggests practical implications for incorporating mindfulness and spiritual development interventions in educational and financial counselling contexts.
