Kavishri - Sikh Poetry
In which Granth can I find Rehat Maryada? Is it in Sri Dasam or Sri Sarabloh Granth?
You can't find Rehat Maryada in any Gurbani Granth. It is a collection of codes of conducts written by contemporary Sikhs of the times of Guru Gobind Singh - but it does include Gurbani to refer to how we should live & conduct ourselves.
