Guru Nanak Sahib was witness to one of the worst carnage in the history of mankind, to the victimization of natives by the invaders, and to the redefinition of social orders. The Gurbani of Guru Nanak Sahib consequently, is one the most preserved mirrors of the society and circumstances of his time. Consider the following Shabad, This is a very honest and powerful recounting of the horrors of the Mughal invasion under Babur (1483-1530). There are however, two points I would like to enquire about the tuk, * The Mughal invasion of the Indian subcontinent initiated by Babur, and carried further by his heir Humayun (1508-1556) ended in a retreat following huge losses in the Battle of Kannaj(17 May 1540). Humayun's armies retreated to Lahore, and then further back to Sindh (from where he crossed the Sindh river in July 1543 on his way back to Kabul). Now, the Shabad in hand states, These numerical figures, according to most translations and obviously so, refer to the years of Bikrami calendar(Vikram Samvat started in 57 A.D.). I shall provide the various translations of this half-tuk, The 'coming' according to all translations refers to the Mughal invasion. They, however differ in the 'going' part. All translations except the Faridkot Teeka put the year of going at '1540 A.D.' which refers to the retreat of Humayun's armies. The Faridkot Teeka considers the '97 not as 1597 but as 1797 Vikram Samvat. A possible anachronism(in my view) also arises here as most of the historians put Guru Nanak Sahib's Jyoti-jyot year at 1539 A.D. Did then Guru Nanak Sahib simply put the year of Humayun's retreat in this Shabad as the 'end' of atrocities on Punjab's folk(only if we consider other sources which say Guru Sahib did not leave his body till after 1540 A.D., given the 1539 date, even this truns out as a possible 'prophecy'); or did he prophecise the coming of Khalsa in the near future? * The second difficulty I encountered was the interpretation of, The translations are, Who is this 'disciple of man'? Is this a clear prophecy regarding Guru Gobind Singh Sahib or the Khalsa or something else? P.S.- Pardon me for such a long post, but I've been pondering over this Shabad for long and I needed some help interpreting it. Also apologies for such a mess of microdissection and for posting single tuks and even half tuks.
