Nitnem
Nitnem (Punjabi: ਨਿਤਨੇਮ, lit. 'daily routine') is a collection of Sikh hymns (Gurbani) to be read minimally 3 different times of the day. These are mandatory and to be read by every Amritdhari Sikh as expressed in the Sikh Rehat Maryada (the official Sikh Code of Conduct which acts as the ultimate "rulebook" for Amritdhari Sikhs).
