The Harmandir Sahib Development is intended to build a place of worship for men and women from all walks of life and all religions to come and worship God in equality. Therefore, as a nonsectarian universality of Sikhism, Teacher Arjan has specifically invited the Sufi Muslim saint, Hazrat Mian Mir to lay the foundation stone of Harmandir Sahib. The four entrances (representing the four directions) to enter Harmandir Sahib also symbolize the openness of Sikhs to all people and religions. More than 100,000 people visit the holy temple every day to worship, and also participate together in the community kitchen and free food (Langar) regardless of any differences, a tradition that is characteristic of all Sikh Gurdwaras.
The Gurdwara which was currently renovated in 1764 by Jassa Singh Ahluwalia with help from other Sikh Missions. In the early 19th century, Maharaja Ranjit Singh secured the Punjab area from outside attacks and covered the gurdwara's upper floor with 750 kg of gold, which gave him a distinctive appearance and English name.
