Every night, the Granth Sahib is carried in procession along this bridge to its "bed" in the Akal Takht, the seat of the Sikh parliament (built 1609). Called the Palki Sahib, this nightly ceremony provides a chance for all male pilgrims and visitors to actively participate in the veneration of the Holy Book. Lines form in front of and behind the heavy palanquin and each man shoulders the burden for a few seconds before passing it along, forming a human conveyer belt that allows everyone to participate and everyone to rest. The ceremony usually takes place at 11pm in summer at 9:30pm in winter.
