HANOI, VIETNAM • Thich Nhat Hanh, the revered Zen Buddhist monk who helped spread the practice of mindfulness in the West and socially engaged Buddhism in the East, has died. He was 95.

The death was confirmed by a monk at Tu Hieu Pagoda in Hue, Vietnam who said that Nhat Hanh, known as Thay to his followers, died at midnight on Saturday.

A post on Nhat Hanh’s verified Twitter page attributed to The International Plum Village Community of Engaged Buddhism also confirmed the news, saying, “We invite our beloved global spiritual family to take a few moments to be still, to come back to our mindful breathing, as we together hold Thay in our hearts.”

Born as Nguyen Xuan Bao in 1926 in Hue and ordained at age 16, Nhat Hanh distilled Buddhist teachings on compassion and suffering into easily grasped guidance over a lifetime dedicated to working for peace. In 1961 he went to the United States to study, teaching comparative religion for a time at Princeton and Columbia universities.

For most of the remainder of his life, he lived in exile at Plum Village, a retreat center he founded in southern France.

There and in talks and retreats around the world, he introduced Zen Buddhism, at its essence, as peace through compassionate listening. Still and steadfast in his brown robes, he exuded an air of watchful, amused calm, sometimes sharing a stage with Tibetan Buddhist leader Dalai Lama.

The Dalai Lama said he was saddened by the death of “his friend and spiritual brother.”

Surviving a stroke in 2014 that left him unable to speak, Nhat Hanh returned from France to Vietnam in October 2018, spending his final years at the Tu Hieu Pagoda, the monastery where he was ordained nearly 80 years earlier.

Nhat Hanh plunged into anti-war activism after his return to his homeland in 1964 as the Vietnam War was escalating. There, he founded the Order of Inter-being, which espouses “engaged Buddhism” dedicated to nonviolence, mindfulness and social service.

In 1966, he met the U.S. civil rights leader Martin Luther King Jr. in what was a remarkable encounter for both. Nhat Hanh told King he was a “Bodhisattva,” or enlightened being, for his efforts to promote social justice.

In his exchanges with King, Nhat Hanh explained one of the rare controversies in his long life of advocating for peace — over the immolations of some Vietnamese monks and nuns to protest the war.

“I said this was not suicide, because in a difficult situation like Vietnam, to make your voice heard is difficult. So sometimes we have to burn ourselves alive in order for our voice to be heard so that is an act of compassion that you do that, the act of love and not of despair,” he said in an interview with U.S. talk show host Oprah Winfrey. “Jesus Christ died in the same spirit.”

Both North and South Vietnam barred Nhat Hanh from returning home after he went abroad in 1966 to campaign against the war, leaving him, he said, “like a bee without a beehive.”

He was only allowed back into the country in 2005, when the communist-ruled government welcomed him back in the first of several visits. Nhat Hanh remained based in southern France.
