Did you know how did the tradition of taking the form of Guru Granth Sahib from Darbar Sahib to Akal Bunga at night started?
Bunga Akaliyan or Akal Bunga was the residence of Akali Baba Phula Singh. He and the people of his misl (Akali) used to take care of Darbar Sahib and other gurdwaras. After reciting the Guru Granth Sahib at night, he would take the Saroop (Bir) of the Guru Granth Sahib to a special room in his Bunga for security. In the morning Saroop of Guru Granth Sahib would be taken from that room to Darbar Sahib again.
The reason for this was that no one was present in Darbar Sahib at night and there were no doors (doors of Darshani Deodhi); Due to this, sometimes animals used to come to Parikarma at night. The gates were erected by Giani Sant Singh after 1823.
A few years after the death of Akali Phula Singh (1823), Gurmukh Singh (son of Sant Singh Giani) occupied the Bunga and made it his abode. Although Akali Phula Singh was dead, to protect the Guru Granth Sahib at night, Saroop was kept in a special room in the Bunga of Akalis following the previous tradition ( where it is still kept at night, bringing from Darbar Sahib after Sukhaasan ).
Around 1840, Gurmukh Singh and Darbara Singh, the granthi of Darbar Sahib, wrote 'Gur Bilas Patshahi Chhevin' and started calling the Akalis' Bunga to Bunga Akal Takht and started building a gurdwara here, which later came to be known as Akal Takht Sahib.
