The TM organization (Transcendental Meditation) staged a week-long meditation with 7000 people together in about 1984. I was there in Fairfield, Iowa. Pretty interesting stuff happened. THey also, back in 1979 or so, sent hundreds of volunteers to surround war zones and meditate all day every day, for 30 days. They sent social scientists to study the effects. Apparently the acts of violence decreased, the economy improved, and hospital admissions dropped. We had a similar effect in prisons when teaching TM there, as I did in San Quentin, in the 1980's. Even non-meditators seemed to change their behavior.
