In the 1960s, at the height of the Vietnam War and the Buddhist crisis in Southern Vietnam, Thich Nhat Hanh formulated his vision of “Engaged Buddhism” (Đạo Phật đi vào cuộc đời) in war-torn Saigon. Fast forward to the contemporary period, a new generation of urban Buddhists, both monastics and lay, is re-inventing what engaged Buddhism can mean in post-war, post-economic reform Ho Chi Minh City. Combining archival research with extensive ethnographic fieldwork at Buddhist temples and institutions in Ho Chi Minh City from 2016 to 2018, this paper examines continuities and changes in urban Vietnamese engaged Buddhism, with a special focus on a comparison of the roles of lay urban Buddhist youth in the conceptualization and implementation of engaged Buddhism in the 1960s and the contemporary period. I argue that to understand Vietnamese engaged Buddhism, it is imperative that we consider the diverse range of social, religious, and political aspirations of youth in both time periods and carefully examine how Buddhism is interwoven with the narratives and reflections of youths about their generation. While this continues many imperatives surrounding social and political welfare of Buddhism of the 1960s, I show that with the popularization of Thich Nhat Hanh’s post-war mindfulness meditation practices, new communication technologies, and recent models of Buddhist “industrialized philanthropy” (Weller et al. 2018), contemporary engaged Buddhism in Ho Chi Minh City proposes novel approaches to social activism, citizenship, and education that foster a new late-socialist Buddhist public and community.
