Thích Nhất Hạnh
During the Vietnam War
Vạn Hạnh University was taken over by one of the chancellors, who wished to sever ties with Nhất Hạnh and the SYSS, accusing Chân Không of being a communist. Thereafter the SYSS struggled to raise funds and faced attacks on its members. It persisted in its relief efforts without taking sides in the conflict.
Writings
During his long exile, Nhất Hạnh's books were often smuggled into Vietnam, where they had been banned.
Later activism
In 2014, major Jewish, Muslim, Hindu, Buddhist, Anglican, Catholic and Orthodox Christian leaders met to sign a shared commitment against modern-day slavery; the declaration they signed called for the elimination of slavery and human trafficking by 2020. Nhất Hạnh was represented by Chân Không.
