Dom John Main, O.S.B. (1926–1982), was a Benedictine monk and priest who presented a way of Christian meditation which utilized the practice of a prayer-phrase or mantra. In 1975 Dom John began Christian meditation groups which met at Ealing Abbey, his monastery in West London, England and, later, in Montreal, Canada. These were the origins of the ecumenical network of Christian meditation groups which have become the [World Community for Christian Meditation][1] (WCCM).
