Eric Kruszewski is a Baltimore-native, who started traveling internationally in 2005. He is drawn to new cultures, faces, practices and daily life. His website features galleries from Tibet, Mongolia, India, Georgia, and closer to home, Alaska and the American West. Spend some time at Eric's Mongolia gallery, which has some nice photographs of the Naadam festival.
The above photograph is of Tibetans prostrating themselves in Lhasa. Prostration is an important expression of Tibetan Buddhism. It's said that Tibetans are expected to prostrate themselves 100,000 times a year. Although they prostrate themselves at temples, some pilgrims cover the entire 33-mile route around Mount Kailas by repeatedly prostrating themselves.
The first time I saw a Buddhist pilgrim prostrating himself in such a way was at the Boudhanath Stupa in Kathmandu, about 10 years ago. He wore a full-body leather apron, and wooden "clogs" for his hands, and he circumambulated the stupa for as long as I was there.
