Nitnem (Punjabi: ਨਿਤਨੇਮ) (literally 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 Sikh as expressed in the Sikh Rehat Maryada. Optionally additional prayers may be added to a Sikh’s nitnem. There are five hymns (Five Banis) to be done during Amrit Vela (early morning) the Rehras Sahib hymn for the evening and Kirtan Sohila for the night, The morning and evening prayers should be followed by an Ardaas. The nitnem has been compared to the Islamic prayers, which also consist of five prayers a day at prescribed times.
The Sukhmani Sahib is a set of 192 gurbani (hymns) recorded in the Guru Granth Sahib, the main scripture of Sikhism. The gurbani were written in the 16th century by Guru Arjan (1563–1606), the fifth of the ten Sikh gurus. In the Guru Granth Sahib, the Sukhmani Sahib is recorded on ang 262.
The Sukhmani Sahib is divided into 24 sections (called ashtpadi), each of which contains eight gurbani. Ashtpada is the Sanskrit word for a verse that has eight (asht) metrical feet (pādi).
Gurbani from the Sukhmani Sahib are frequently recited by Sikhs, either in a place of worship (gurdwara) or at home. Reciting the entire Sukhmani Sahib takes about 90 minutes, and is normally undertaken by everyone in the gurdwara’s congregation. The term sukhmani comprises two words: sukh (peace) and mani (treasure). Reciting gurbani is believed to bring peace to one’s mind and to the world.
