The ceremony can be repeated multiple times to extend the duration of the marriage. Both the bride and the groom may try to affect the result of the ritual, for example, the bride can tie the knots very tightly, while the groom can decide to only untie a certain number of the knots before the hymn ends. The number of knots the groom undoes before the hymn ends determines the number of years that their marriage will last. During the wedding ceremony, the bride will sing a hymn to the Lady of the Skies while the groom attempts to undo a series of knots that the bride has tied in a long rope. The Avvar do not marry for life, instead, they practice temporary marriages.
