It is when Guru Sahib was made to sit on the red hot iron pan and burning sand was being poured over His body. His friend and devotee, Mia Mir ( Spelled as Mian Mir also), rushed to see him. Mia Mir was a Muslim saint. When he saw the ghastly scene, he cried out and said, “O Master! I cannot bear to see these horrors inflicted upon you. If you permit me, I would demolish this tyrant rule (Mian Mir is said to have possessed supernatural powers at that time)." The Guru smiled and asked him to look towards the skies. It is said that Mian Mir saw Angels begging the Guru's permission to destroy the wicked and the proud.
The Guru addressed him,"Mia Mir, you are perturbed too soon. This is the Will of my Master (God), and I cheerfully submit and surrender to His Sweet Will." The Guru repeated and exemplified in action the meaning of this verse:
qyrw kIAw mITw lwgY ]
hir nwmu pdwrQu nwnku mWgY ]
Mia Mir asked, why was he enduring the suffering at the hands of his vile sinners when he possesses superpowers? The Guru replied,"I bear all this tyranny to set an example to the Teachers of True Name, that they may not lose patience or rail at God in affliction. The true test of faith is the hour of misery. Without examples to guide them, ordinary persons' minds quail in the midst of suffering." Upon this Mia Mir departed commending the Guru's fortitude and singing his praises.
It all happened at Lahore, MY MISTAKE, THANKYOU FOR REMINDING ME.
