The Diwan Hall is the sacred space where Guru Granth Sahib Ji is enshrined. Guru Granth Sahib Ji, the 11th Guru of the Sikhs, serves as the ultimate source of spiritual and moral guidance. Its pages contain holy scriptures, hymns, and musical compositions written, composed, and compiled by the Sikh Gurus, as well as by Hindu and Muslim saints.
Guru Granth Sahib Ji is reverently placed on a raised platform, covered by a canopy called "chanani," while the entire congregation (sangat) sits cross-legged on the carpeted floor, facing the Guru. This seating arrangement symbolizes equality and humility. At the Guru Gobind Singh Gurdwara, it is customary for females to sit on the left and males on the right.
Traditionally, women, children, and men sit on opposite sides of the Diwan Hall. However, a mixed seating pattern is not prohibited. Guru Granth Sahib Ji is placed on pillows, adorned with beautifully draped cloths called "Romallas," which cover it when it is not being read.
The front of the Diwan Hall houses Guru Granth Sahib Ji, and nearby, another platform accommodates musicians known as the Ragis. They play their instruments while the congregation joyfully sings hymns. Music holds great importance in Sikh worship as it enhances the experience of singing the hymns written in Guru Granth Sahib Ji, known as Gurbani, which translates to "The words of the Guru."
