Positive psychology, founded by Seligman and Csikszentmihalyi, shifted the discipline's focus from pathology to the conditions that enable human flourishing: strengths, meaning, relationships, and engagement. The concept of flow — complete absorption in a challenging activity — maps onto the Sutras' description of dhyāna, the sustained, effortless contact with a chosen object. Attending to what is working, not only what is broken, is not optimism bias but a methodologically sound approach to the full range of human possibility.
Each step builds on the last.
