Explanation:

The laava phere (singular laav) are the four hymns of the Anand Karaj (Sikh wedding ceremony) which form the main part of this ceremony. The four hymns are from the Guru Granth Sahib, the Sikh holy scriptures and appear on Ang 773 to 774 of the total of 1430.

Guru Ram Das says on Ang 788 of the Sri Guru Granth Sahib of the meaning of marriage to a Sikh couple: "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." The four laava give the Sikh couple spiritual guidance for their life ahead.
