This spring and summer, a phenomenal new documentary has been touring the United States, but if you don't live in one of the cities or towns on its itinerary, or if you do but happen to blink while it's being screened (most likely at just one art house cinema, and just for a couple of days), you've probably never heard about it.

The Dhamma Brothers is about the transformative power of an ancient Indian mediation practice called Vipassana, and its ability to affect a most unlikely population: inmates of a maximum security prison southwest of Birmingham, Alabama.

This trailer provides a glimpse of the film's artfulness, and the beauty of its message.

The documentary has yet to open in a number of cities, including Chicago, Seattle, and Cleveland. Check the screening schedule here to see if it's coming to a theater near you.

And lest you think this is just the wishful thinking of armchair liberals, you can read a thorough report on Vipassana's benefits for prisoners' lives while incarcerated as well as their re-integration into society upon release here.
