This group was inspired by the teachings of the Benedictine monk, John Main, who died in 1982. I was fortunate enough to come across some tapes of his teachings some years ago -- to my very real benefit.
Here's a little quotation from the site:
It has become more and more evident in recent years that meditation, as a way of tolerance and compassion, builds a bridge of the spirit between peoples of different faiths, between rich and poor, and between all those suffering conflict or division. The great social and psychological distresses of modern society call for a deep contemplative response. John Main believed that each human being, whatever their lifestyle, is called to this contemplative depth.
