Shinzen Young (真善, Shinzen) is an American meditation teacher. He leads residential and phone-based meditation retreats for students interested in learning the Vipassana (insight) tradition of Buddhism. Although Vipassana is traditionally a Theravada technique, Shinzen was originally ordained in Japan as a monk in the Shingon (Japanese Vajrayana) tradition. He has studied and practiced extensively in other traditions, including Zen and Native American traditions.
