Summary: All ancient wisdom teachers tell us that if we want to live with a deep, abiding sense of true happiness, we need to live with virtue. Modern science, of course, confirms this ancient wisdom. In fact, the entire field of Positive Psychology was founded on the idea that we need to live in integrity with the core virtues taught by all major wisdom traditions: Courage, Self-Mastery, Integrity, Wisdom, Love, and Transcendence.
