With Vatican approval, Brother David became a leading voice in Buddhist-Christian dialogue and co-founded Grateful Living, an international organization inspiring millions to live with mindfulness, compassion, and joy. Having celebrated his 100th birthday in July 2026, his lifelong message remains simple yet profound: “Everything is a gift. The degree to which we are awake to this truth is a measure of our gratefulness, and that gratefulness is a measure of our aliveness.”
