Explanation:

In September 1708, Guru Gobind Singh, who had come to the Deccan along with the Mughal Emperor, Bahadur Shah, happened to go to Madho Das’(Banda Bahadar) hut while hunting.
He encouraged him to give up his present recluse lifestyle and the lonely way of living. The Guru asked him to resume the duties of a true warrior to fight for righteousness and justice before God. Finding him reluctant, the Guru deputed Madho Das Bairagi, under the leadership of five Sikhs, to end Mughal persecution of innocents in Punjab and crush the enemies of Khalsa.In a few days, the Guru held a darbar and on 3 September 1708, baptised Madho Das with Khanda di pahal and conferred the title of Banda Singh Bahadur on him. He appointed him as his military lieutenant and invested him with full political and military authority as his deputy to lead the campaign in the Punjab against the evil Mughal administration and to punish Nawab Wazir Khan and his supporters.
