It is said that Torajans are people who “live to die”. For this Indonesian ethnic group, funerals are such extravagant events that they sometimes attract tourists. Families can postpone burials years (and the deceased are considered sick and hosted at home until the funeral) until the family can raise enough money and gather as many relatives as possible. And then it’s a jubilant multiday social event with a parade, dances and animal sacrifices. Agung Parameswara photographed these funerary practices when he traveled to South Sulawesi province, where the Torajans live. (Photo by Agung Parameswara/The Washington Post)
