You might say "till death do us part," but the Toraja people on the Indonesian island of Sulawesi think that it's nonsense. Every year they celebrate the "Ma'nene," which roughly translates "The Ceremony of Cleaning of Corpses." Families go to the tombs of their dead relatives, dig up their remains, clean up the corpses, dress them up in fresh clothing and parade them around the village.
Indonesia might be a Muslim country, but the Tana Toraja are mostly Protestant Christian. However, there's a degree of syncretism involved, as the locals still practice some of their old, animistic traditions. The Toraja Church has tried to stop Ma'nene, but the ancestor worship runs deep in the culture.
For Torajans, death is barely a parting. The dead are mummified and put into ornate, colorful coffins. There, they spend month and even years in their own homes, before getting a funeral - that time is needed for the family to raise enough money for the feast. In fact, families can go into debt to raise enough money for the festivities!
Before the burial, the relatives still talk to their passed away loved ones, offering them food and drink, as well involving them in family gatherings.
