During the rite of sindoor daan under a sheet, Trevor is putting vermilion powder, known as sindhur/sindoor, in the part of Indera's hair, which signifies that she is his wife. When they emerge, they are considered to be married.
Katrina Thomas's notes: Indo-Guyanese are Hindus twice removed from their homeland. Imported as indentured laborers to British Guiana in the 19th century to work the sugar plantations, they now make up half the population there. In the 1980's, some emigrated to the US, mostly to Queens, NY, but not to established Hindu neighborhoods. Their weddings have a special format, which include some elements that adhere to Hindu custom. I photograph several. One is performed outdoors at the bride's home, situated apart from their neighborhood. The others are conducted in a temple within the community.
