Thich Nhat Hanh, a Vietnamese Buddhist monk who was one of the world’s most influential Zen masters, spreading messages of mindfulness, compassion and nonviolence, died Saturday at his home in the Tu Hieu Temple in Hue, Vietnam. He was 95.

The death was announced by Plum Village, his organization of monasteries. He suffered a severe brain hemorrhage in 2014 that left him unable to speak, though he could communicate through gestures.

A prolific author, poet, teacher and peace activist, Thich Nhat Hanh was exiled from Vietnam after opposing the war in the 1960s and became a leading voice in a movement he called "engaged Buddhism,” the application of Buddhist principles to political and social reform.
