Explanation:

The second fortnight of December 1704 was the most difficult and critical period in the life of Guru Gobind Singh Ji. It was during this period that forty Majhail Sikhs had deserted the Guru, the city of Anandpur had to be vacated, the Sarsa floods had brought havoc, Guru Ji's family had become separated, his two elder sons had died before his own eyes and the Guru himself had to escape from Chamkaur Sahib towards Machhiwara jungle. Even at Machhiwara he was surrounded by enemy forces from all sides.

In the jungle Guru Ji met two Pathan brothers Nabi Khan and Ghani Khan who were dressed in blue, he asked them to prepare similar clothes for him. In the mean time Guru Ji sent for Sayyad Inayat Khan, one of his followers who lived nearby. Guru Ji entrusted him with a letter that was addressed to Emperor Aurangzeb for safe keeping. Using the blue garments, Guru Ji disguised himself as Uch-Ka-Pir (a holy man from Uch) and with his companions Nabi Khan and Ghani Khan on one side and Bhai Dharam Singh and Bhai Mann Singh on the other they set off towards the village of Ghulal.
