(Reuters) -Thich Nhat Hanh, the Zen Buddhist monk, poet and peace activist who in the 1960s came to prominence as an opponent of the Vietnam War, died on Saturday aged 95 surrounded by his followers in the temple where his spiritual journey began.

"The International Plum Village Community of Engaged Buddhism announces that our beloved teacher Thich Nhat Hanh passed away peacefully at Tu Hieu Temple in Hue, Vietnam, at 00:00hrs on 22nd January, 2022, at the age of 95," said his official Twitter account.

His week-long funeral will be held at the temple in a quiet and peaceful manner, according to his followers.

"Thich Nhat Hanh will be remembered as arguably one of the most influential and prominent religious leaders in the world," Chargé d'Affaires Marie C. Damour of the U.S. Mission to Vietnam said in a statement.

"Through his teachings and literary work, his legacy will remain for generations to come," she said, adding that his teachings, in particular on bringing mindfulness into daily life, have enriched the lives of innumerable Americans.

In a body of works and public appearances spanning decades, Thich Nhat Hanh spoke in gentle yet powerful tones of the need to "walk as if you are kissing the earth with your feet".

He suffered a stroke in 2014 which left him unable to speak and returned to Vietnam to live out his final days in the central city of Hue, the ancient capital and his place of birth, after spending much of his adult life in exile.

As a pioneer of Buddhism in the West, he formed the "Plum Village" monastery in France and spoke regularly on the practice of mindfulness - identifying and distancing oneself from certain thoughts without judgement - to the corporate world and his international followers.

"You learn how to suffer. If you know how to suffer, you suffer much, much less. And then you know how to make good use of suffering to create joy and happiness," he said in a 2013 lecture.

"The art of happiness and the art of suffering always go together".

Born Nguyen Xuan Bao in 1926, Thich Nhat Hanh was ordained as a monk as modern Vietnam's founding revolutionary Ho Chi Minh led efforts to liberate the Southeast Asian country from its French colonial rulers.

Thich Nhat Hanh, who spoke seven languages, studied at Princeton Theological Seminary and taught at Columbia University in the United States in the early 1960s. He returned to Vietnam in 1963 to join a growing Buddhist opposition to the U.S.-Vietnam War, demonstrated by self-immolation protests by several monks.

"I saw communists and anti-communists killing and destroying each other because each side believed they had a monopoly on the truth," he wrote in 1975.

"My voice was drowned out by the bombs, mortars and shouting".

"Venerable Thich Nhat Hanh lived a truly meaningful life. I have no doubt the best way we can pay tribute to him is to continue his work to promote peace in the world," the Dalai Lama, the spiritual leader of Tibetan Buddhism, said on Twitter.

'LIKE A PINE TREE'

Towards the height of the Vietnam War in the 1960s he met civil rights leader Martin Luther King, whom he persuaded to speak out against the conflict.

King called Thich Nhat Hanh "an apostle of peace and non-violence" and nominated him for the Nobel Peace Prize.

"I do not personally know of anyone more worthy of the Nobel Peace Prize than this gentle Buddhist monk from Vietnam," King wrote in his nomination letter.

While in the United States to meet King a year earlier, the South Vietnamese government banned Thich Nhat Hanh from returning home.

Fellow monk Haenim Sunim, who once acted as Thich Nhat Hanh's translator during a trip to South Korea, said the Zen master was calm, attentive and loving.

"He was like a large pine tree, allowing many people to rest under his branches with his wonderful teaching of mindfulness and compassion," Haemin Sunim told Reuters.

"He was one of the most amazing people I have ever met."

Thich Nhat Hanh's works and promotion of the idea of mindfulness and meditation have enjoyed a renewed popularity as the world reels from the effects of a coronavirus pandemic that has killed over a million people and upended daily life.

"Hope is important, because it can make the present moment less difficult to bear," Thich Nhat Hanh wrote. "If we believe that tomorrow will be better, we can bear a hardship today.

"If you can refrain from hoping, you can bring yourself entirely into the present moment and discover the joy that is already here."
