In 1981, a Buddhist monk teaching at the University of Madison, Wisconsin, made the bold request of the Dalai Lama to come and perform a rare ritual, never before done outside of India or Tibet: the Kalachakra, among the highest of the Buddhist tantric teachings. In just a few months, with a team of dedicated students, and cameras rolling, they constructed a temple and organized an event for over a thousand spiritual seekers, in a cornfield outside Madison.

The incredible footage was tucked away in the Smithsonian vaults, until now. What unfolds is the story of a powerful ritual, its impact on the people that made it happen, and the meaning behind this ancient initiation.
