Having originated in mainland China one hundred years ago, Yiguandao is a fast growing religious movement and one the largest religions in Taiwan, where it relocated the center of its activities in the mid-20th century. Today, it exists as a highly adaptive transnational religious movement devoted to self-cultivation and social harmony. Moreover, in contrast with other Chinese religious traditions, the group’s millenarian teachings lend believers a sense of urgency as they carry out proselytizing activities across the world.
