The term Naam refers to the act of worship of God by Sikhs. Naam Japo refers to the meditation, vocal singing of Hymns from the Sri Guru Granth Sahib or of the various Names of God, specially the chanting of the word Waheguru, which means Wonderful Lord. Singing of hymns generally is also referred to a ‘Naam Jap’, sometimes also called ‘Naam Simran’.

Naam Japo is a main pillar of Sikhism and is the term used to refer to this very important activity in the everyday life of a Sikh — the singing, quiet meditation, listening of sacred text or sacred words. Critical importance is given to the meditation in the SGGS.
