Summary of Findings
Following the retreat, inmates showed significant gains in mindfulness and emotional intelligence, sustained reductions in mood disturbance, and a 40% drop in rule infractions.
These findings, in a population of life-sentenced violent offenders, suggest that Vipassana meditation supports lasting behavioral improvements that contribute to institutional safety and stability.
