The marriage is performed in some phases such as the role of matchmaker to find the boy and the girl to exchange the proposal to each other family, Paka Kotha- a boy and meet girl, panchini or engagement, Gaye Holud, and Final Marriage. The first event in a wedding is an informal one: the groom presents the bride with a ring marking the "engagement" which is gaining popularity. For the mehendi shondha the bride's side applies henna to each other as well as the bride for the bride's Gaye Holud, the groom's family - except the groom himself go in procession to the bride's home. This is more or less the Muslim wedding procession. Hindu weddings also follow the same parts of the wedding but the wedding part is somewhat different. The wedding is done along with a feast and according to the Hindu religion's wedding steps, Shat-pake-badha; Sidur Daan etc. The wedding most likely lasts the whole night starting in the evening. The Christian and Buddhist Wedding follow a totally different Process. They more or less follow Western Culture and Methods. Sometimes they too follow the Bengali wedding procession.
So witness a typical Bangladeshi marriage and have a life-time experience you can visit Bangladesh.
