The Fifth Guru Nanak, Sahib Sri Guru Arjan Dev Ji, finished compiling the , now commonly known as Sri Guru Granth Sahib or in 1604 A.D. According to the prevalent procedure followed by authors of religious literature, Sri Guru Granth Sahib was started with the praise of the Almighty God in the form of . After completing the Volume, the closing Shabad of Mundavani M.5 was put at the end as the closing Seal (the word Mundavani is derived from the word , i.e., to close), and was, of course, followed by the last thanksgiving shabad: ...
While compiling the contents of Sri Guru Granth Sahib, Guru Sahib devised and adopted a very meticulous system of checks and balances so that no extraneous material could be interpolated anywhere without being discovered. Each entry herein is numbered and subtotals of each part are caaried forward to form the grand total. It was thus not possible for any miscreant to introduce any extraneous matter in the main body of Sri Guru Granth Sahib.
