<p>This study offers a comprehensive understanding of workplace spirituality, employee demography, and subjective happiness for organizational success in India which are characterized by intense competition and workforce diversity. It employs a mixed methods approach and mixes the findings of quantitative and qualitative study to analyze it under the lens of Integral Theory of Spirituality. In study 1, data collected from 620 professionals from India who practice mindfulness is analyzed to examine the effects of four key constructs of workplace spirituality—meaningful work, mindfulness, compassion, and transcendence—on general subjective happiness and the moderating effects of demographic factors viz., gender, marital status, education, and age. Findings reveal meaningful work and mindfulness predict subjective happiness and that single, younger women professionals with bachelor’s degree respond more to workplace spirituality and report higher levels of subjective happiness. Study 2 analyses the interviews of fourteen young, single women professionals who practice mindfulness. Mindfulness techniques help in gaining professional clarity, managing stress, and fostering compassion, and personal fulfillment. By integrating the Integral Theory of Spirituality, which links personal and collective growth, this research provides a nuanced framework for understanding how workplace spirituality can promote subjective happiness. The findings offer valuable implications for business ethics in organizations in emerging markets, suggesting that cultivating workplace spirituality tailored to demographic needs can foster happier, more engaged employees, contributing to long-term organizational success.</p>
