Main died of cancer, at the Benedictine monastery in Montreal in 1982. Freeman continued Main's work, travelling widely to establish Christian meditation groups across the world. In 1991, these Christian meditation groups were networked together into the World Community for Christian Meditation (WCCM). Each year the WCCM hosts the John Main Seminar, which has been led by Mary McAleese, Huston Smith, Charles Taylor, Father William Johnston, Father Richard Rohr OFM, Sister Joan Chittister OSB, Anglican archbishop Rowan Williams, Greek Orthodox bishop Kallistos Ware, Abbot Thomas Keating, Dom Bede Griffiths and the 14th Dalai Lama, among others.
