Kirtan Sohila compiles five short hymns composed across three different Gurus, Guru Nanak, Guru Ramdas and Guru Arjan, rather than being the unified composition of a single author, making it, despite its brevity, one of the more explicitly multi authored of the fixed daily Sikh liturgical texts, comparable in that respect to the assembled, multi Guru structure of the considerably longer evening prayer Rehras Sahib recorded elsewhere in this atlas, though compressed here into a much shorter nightly office.
A recurring theological image across the included hymns, well documented in Sikh theological commentary, treats death and union with the divine through the metaphor of a wedding night, the soul understood as a bride approaching final union with the divine bridegroom, a metaphor that gives the text's dual use, recited both at bedtime and over the dead, an internal coherence rather than being an arbitrary pairing of two unrelated occasions: sleep and death are treated in the text's own imagery as related transitions, a nightly small letting go that rehearses the larger, final one, which is part of why Sikh teaching considers reciting the same short set of hymns appropriate to both moments. This bridal metaphor for death is not unique to Sikh scripture, drawing on devotional imagery with parallels across earlier North Indian bhakti poetry more broadly, but its specific placement here, in a text said both nightly and at the graveside, gives the shared image unusual practical weight in ordinary Sikh religious life.
