On the coin, I wonder what the Arabic writing beneath the Gurmukhi is?

simple answer : My Waheguru makes no mistakes so there's nothing to correct...

well said, it's a hukam simple as.  But to be fair, there are probably spiritual reasons for letting hair grow to it's full length, even probably physical benefits.. but as sikhs we should just follow Guru's Hukam.  

lmao. Why do insecure people like you always bring the topic to themselves?
