Anand Karaj
The standard Sikh marriage ceremony known as the Anand Karaj is centered around a four-stanza hymn composed by Guru Ram Das ji. During the marriage ceremony the couple circumscribe the Guru Granth Sahib ji as each stanza of the Lawan is read. The first round is the Divine consent for commencing the householders life through marriage. The second round states that the union of the couple has been brought about by God. In the third round the couple is described as the most fortunate as they have sung the praises of the Lord in the company of saints. In the fourth round the feeling of the couple that they have obtained their hearts' desire and are being congratulated is described.
Guru Ram Das Sahib composed a beautiful bani called Laavan about the meaning of marriage to a Sikh couple. Effectively, the Guru defines a Sikh marriage as a spiritual union in these two lines: "They are not said to be husband and wife who merely sit together. Rather they alone are called husband and wife, who have one soul in two bodies."
