The domestic layer is where most Sikh religion actually happens and it is the least documented part of the tradition. A gutka — a pocket-sized book of the daily banis — is kept wrapped in cloth on a high shelf, and opened with the head covered and hands washed; recordings and phone apps have partly replaced it and older Punjabis mind about that. Families with space and confidence install a full Guru Granth Sahib in a dedicated room, which brings the full protocol with it: a canopy, a bed, prakash in the morning and sukhasan at night, and no shoes or smoking anywhere near. Sikh institutions actively discourage households from taking that on unless they can maintain it, and gurdwaras in Britain and Canada now run collection services for family copies that have been neglected. Alongside all this sit practices the code disapproves of — a photograph of Guru Nanak garlanded on the wall, a red thread, a chosen auspicious date for a house move — and they persist comfortably in the same rooms.
