Brother David Steindl-Rast is a Benedictine monk, author, and lecturer widely recognized for his commitment to interfaith dialogue and his emphasis on gratitude as a transformative spiritual practice. Born in Vienna in 1926, he survived the challenges of World War II before emigrating to the United States in 1952. He entered monastic life at Mount Saviour Monastery and went on to engage deeply with both Christian and Buddhist traditions, studying with notable Zen masters. His work bridges spirituality and science and has led him to collaborate with religious and cultural figures across traditions. He co-founded the Center for Spiritual Studies and A Network for Grateful Living, advocating for gratefulness as essential to human flourishing. His writings include Gratefulness, the Heart of Prayer and Belonging to the Universe (with Fritjof Capra). Known for his mystical approach, he describes religion as a living flame that must be rediscovered beneath layers of doctrine, ritual, and dogma.
