[6][4] The worship centres were built as a place where Sikhs could gather to hear the guru give spiritual discourse and sing religious hymns in the praise of Waheguru.
Even houses have been turned into dharamsalas where kirtan was sung on the eve of Vaisakhi.”Guru Nanak set-up an important dharamsal in the new-found Kartarpur after settling there.
[4] Other important dharamsals were located in Khadur, Goindwal, Ramdaspur, Tarn Taran, Kartarpur (Doaba) and Sri Hargobindpur, all of whom had been directly founded upon the instruction of a Sikh guru.
[4] Passionate early Sikhs would found dharamsals at various places across the Indian subcontinent and in Afghanistan as a means of expressing their devotion to the faith.
[4] Udasis were commanded by Guru Hargobind and his successors to found dharamsals in the distant reaches of the subcontinent far from the nucleus of Sikh centrality and rejuvenate the abandoned, dilapidated, or struggling dharamsals which had been founded by Guru Nanak and his followers in faraway places, which struggled due to their extreme distance from the central Sikh authority located mainly in Punjab.
[4] Guru Tegh Bahadur founded new dharamsal centres during his missionary tours of the Malwa region of Punjab and in northeastern India.
[4] This was especially true in the rural areas, villages, and small towns where most of the local Sikh congregations consisted of simple peasants with little means of wealth.
[4] They were not built upon a specific axis because Sikhs believe God is omnipresent and the entire Earth is divine and equally fitting as such.
[4] The dharamsals likely did not contain intricate and ornate furniture, fittings, and other decorative accessories, unlike modern-day gurdwaras.
[4] The dharamsals incorporated a langar (communal kitchen) and lodge, especially the ones on important highways and trade routes, where persons could eat and stay without discriminated based upon their religious or caste-background.
The use of 'sahib', as sometimes appended in the term Gurdwara Sahib, derives from a loanword of Arabic origin, meaning "companion" or "friend".
[11] The Panj Takht which literally means five seats or thrones of authority, are five gurdwaras which have a very special significance for the Sikh community.
The Nagar Kirtan, a Sikh processional singing of holy hymns throughout a community, begin and conclude at a gurdwara.
The main philosophy behind the langar is two-fold: to provide training to engage in seva and an opportunity to serve people from all walks of life, and to help banish all distinctions between high and low or rich and poor.
In the 21st century, more and more gurdwaras (especially within India) have been following the Harimandir Sahib pattern, a synthesis of Indo-Islamic and Sikh architecture.
During recent decades, to meet the requirements of larger gatherings, bigger and better ventilated assembly halls, with the sanctum at one end, have become accepted style.
Meditating and understanding the meaning of texts from the Granth Sahib is important for the proper moral and spiritual development of a Sikh.
The gurdwara also serves as a community centre and a guest house for travellers, occasionally a clinic, and a base for local charitable activities.
Apart from morning and evening services, the gurdwaras hold special congregations to mark important anniversaries on the Sikh calendar.
They become scenes of much éclat and festivity during celebrations in honour of the birth and death (Joythi Joyth Samaey) anniversaries of the Gurus and Vaisakhi.
