In the mid-1960s, Thich Nhat Hanh was a little-known Vietnamese Zen monk, touring the United States on behalf of the cause of peace in his homeland. Jim Forest, a Catholic peacemaker, was asked to accompany him on his speaking engagements. From there emerged a friendship over many decades, in which Jim learned through conversations and daily life about Nhat Hanh's spiritual teachings on mindfulness and the inner peace that is necessary for promoting world peace. Over the years Thich Nhat Hanh became one of the most influential and revered spiritual teachers in the world. Jim Forest's intimate portrait, which includes photos and other illustrations, is a unique introduction to a modern spiritual master and his teachings.
