Transcendental Meditation

Transcendental Meditation – TM – was widely popular 40 years ago: a technique for relaxation and awareness using certain sounds and ways of breathing, 20 minutes, twice a day.
You might have thought TM had disappeared, but last winter in Iowa, Lucky Severson found a town where it is flourishing and, for some, controversial: is it just a meditation practice or is it also a religion?
