A gurdwara is the place of worship for Sikhs; however, people from all faiths, and those who do not profess any faith, are welcomed in the Sikh gurdwara. The gurdwara has a Darbar Sahib where the current and everlasting Guru of the Sikhs, the holy scripture Guru Granth Sahib is placed on a Takhat in a prominent central position. The Raagis recite, sing and explain, the verses from the Guru Granth Sahib, in the presence of the holy congregation. All gurdwaras have a Langar hall, where people can eat free vegetarian food. A gurdwara may also have a library, nursery, and classroom. A gurdwara can be identified from a distance by tall flagpoles bearing the Nishan Sahib, the Sikh flag.
