In recent years, psychology has increasingly explored the integration of meditative and psycho-spiritual interventions as mechanisms to enhance emotional wellbeing. This study investigates the impact of a structured psycho-spiritual meditative practice on self-reported happiness levels and perceived stress among Indian adults over a 3-month period. A total of 108 participants were assessed using standardized happiness and stress inventories before and after the intervention. The results demonstrated a highly significant increase in happiness scores (mean difference = 22.20 points, 95% CI: 18.21 to 26.20, p < 0.0001) and a parallel significant reduction in stress scores (mean difference = 11.44 points, 95% CI: 9.87 to 13.02, p < 0.0001), as determined by paired t-tests.

Gender-based subgroup analysis revealed that both male (n = 73) and female (n = 35) participants exhibited substantial improvements in happiness, with mean increases of 20.03 and 26.74 points respectively. However, an unpaired t-test with Welch’s correction indicated no statistically significant gender difference (p = 0.1506). Similarly, stress reduction scores showed no significant difference between males (n = 60) and females (n = 21), suggesting the intervention’s efficacy across gender lines.

Age-related correlation analysis showed a weak negative association between age and happiness gains (r = –0.2192, p = 0.024), indicating that younger participants may benefit slightly more, although the effect size is small. No significant correlation was found between age and stress reduction (r = –0.1168, p = 0.2997).
