The Sikh marriage ceremony is called Anand Karaj. It is performed in the presence of the Guru Granth Sahib, the Sikh scripture. In a Sikh wedding, scripture is read from the Granth Sahib, and after each section the bride and groom walk around the Guru Granth Sahib, showing their commitment to the teachings being read. This is done four times.
Following this, a communal prayer is said for the couple and religious hymns are sung. The ceremony may be performed by any initiated member of the Sikh faith. A specific priest is not required. The prayers being read indicate that the bride and the groom pledge allegiance to each other as well as the Sikh way of life and make a commitment to working together to help each other realize the Divine Presence
