Guru Hargobind introduced the word Gurdwara and any place where the Guru Granth Sahib is installed and treated with due respect can be referred to as a Gurdwara, whether it is a room in ones house of a separate building. Three main functions are carried out in all Gurdwaras.
1) Kirtan - the singing of devotional hymns from the Guru Granth Sahib
2) Reading of the Guru Granth Sahib and its meaning
3) Langar - free community kitchen for all visitors regardless of race, creed, or religion.
Other activities that also take place in Gurdwaras include the provision of libraries of Sikh literature, teaching of Gurmukhi and other charitable work for the community
