This Peace Treaty was developed by Thích Nhất Hạnh and members of Plum Village and published in his book Touching Peace (1992). It may be used as a tool of anger resolution and peace-making. Nhất Hạnh encourages communities to add articles that suit their needs. A commentary is included within the chapter containing the Peace Treaty (Touching Peace, pp. 61-71). The 24-hour limitation is imposed because according to Nhất Hạnh waiting for a longer period can become poisonous to the angry person and to the persons around him or her.
Although the treaty was developed within a Buddhist meditation community, I believe that similar peace treaties can be used within many communities from different backgrounds.
