The late afternoon sun illuminates several glass bottles and other items left as offerings inside a tomb at a Jarai cemetery in the Central Highlands near Kon Tum, Vietnam. The Jarai are the largest of more than two dozen Montagnard, or Dega, hill tribes. They believe the spirits of the deceased linger for a long time, often years, after death, and they build a small house over the grave so the spirit will have somewhere to live. Offerings of food and drink and other items are left inside to appease the spirit before it moves on to the next world. April 14, 2012.
