BIR, a term used for a recension or copy of the Guru Granth Sahib, is derived from Skt. verb vid meaning "to make strong or firm, strengthen, fasten, or to be strong, firm or hard." The Punjabi verb birana which means "to fix, bind or fasten (something) firmly, or to lay (a gun)" is from the same root. Guru Arjan having compiled the Holy Book deputed one of his leading disciples, Bhai Banno, to go and get the volume bound in Lahore, perhaps because facilities for proper binding did not then exist at Amritsar.
CHANGA ,BHAI, a Bhatra scion of Madhav of Ceylon, became a devotee of Guru Nanak. He converted the residence of Madhav into a dharamsala and started imparting instruction in the teachings of the Sikh faith. His name is mentioned in "Haqiqat Rah Muqam," an apocryphal composition included in Bhai Banno\'s bir, i.e. a recension of the Guru Granth Sahib prepared by Bhai Banno, a Sikh contemporary of Guru Arjan.
