The depth and breadth of sustainable development necessitate fresh ideas beyond current attitudes and practices followed by organisations. Organisations need new thinking and enhancement of socially responsible decision-making to construct a sustainable and viable future. In this regard, effective self-management education would be vital in building decision-making ability. However, more research investigation is needed on the ways and means of enhancing the ability of socially responsible decision-making. We propose that Yoga-based practices (YBP) can help us make responsible decisions by enhancing equanimity and emotional awareness to address this need. We report three studies to examine the hypothesis. In Study 1, a survey-based study, we examined the impact of equanimity (EQM) on rational decision-making style (RDMS) mediated by emotional awareness (EA). In Study 2, an experimental vignette based study, we looked at the impact of RDMS on socially responsible decisions (SRD) . Findings from both the studies supported the hypothesised model. In study 3, we examined the impact of YBP on equanimity using pre-post experiment design. The findings of Study 3 suggest that YBP enhances equanimity and that YBP is an effective, efficient, and sustainable training tool for building socially responsible decision-making ability among management students. We discussed the importance and implications of the finding for the field of Management, Spirituality and Religion research. We also contribute to the research domain of Organisation and Management education.
