Though Sikhs are regarded as having their origin from Hindus, but now they are separate entities. They have developed many rituals and customs (since centuries) that are quite different from the Hindus. The marriage is not the exception. Various Sikh Gurus have developed shabad that are recited at the time of marriage which are similar to that of slokas in Hindu marriages.
It is matter to note the Sikh marriage is also a holy union of two souls and it is performed before the holy book “Sri Guru Granth Sahib Ji”. It is similar to performance of Hindu marriage in front of sacred fire. The most sacred ritual of Sikh wedding is the Anand Karaj. It binds the groom and bride in one unit and they become one for the rest of life. The most sacred ritual is performed in the presence of Sri Guru Granth Sahib Ji.
If is believed that the first copule to be wedded with the Anand karaj were the Guru Arjun Dev and Mata Ganga. Now it is core of every Sikh wedding. One the wedding day, the groom along with his family, friends, relatives and other guests reaches at the venue (generally Gurudwara). He is received the bride's parents, family members and guests. Then the shabad is recited in his welcome and thereafter ardas is offered.
There happens the ritual of milni (informal family meeting) and the barat party proceeds to the Darbar Sahib. Sri Guru Granth Sahib Ji is already enthroned there. The bride groom and the bride bow before the Guru and sit in front of Sri Guru Granth Sahib Ji. The shabad is recited and the bride and groom offer special ardas. Their parents also join them in offering ardas.
Then follows the ritual of vak and father of the bride gives the palla in his daughter’s hand. This is followed by slokas. The next step is of Lavan. The lavan is the heart of the Anand Karaj. While the couple make rounds or circles around Guru, the shabad is recited. It makes the marriage and union in deep context of the god. Then brides becomes fully to the groom. The lavan is the union of souls. It consists of four hymns symbolising four vows of the marriage.
Thereafter the first five verses of the Anand Sahib is song. These verses in fact express the joy in union of god. The next shabad expresses joy of bride for acquiring her life partner. The ceremony ends with offering of ardas and sangat. It is meant for blessing of all present there for the couple. Then, a vak at random is recited to give a message for all people present there. This is followed by distribution of Karah Prasad and the bride and groom are garlanded and gifts are presented to them. The couple also receives the rain of flowers by their near relatives and new/fresh garland is kept over the rumalla. This is followed by the langar (or feast) and thereafter the barat returns with the bride.
