I was told that Nanaksar Temple have a Maryada where Granthi ji can take new Hukamnama if the first or second is of scolding or rebuke.
Strong will accept any Hukam
ਜੇ ਗੁਰੁ ਝਿੜਕੇ ਤ ਮੀਠਾ ਲਾਗੈ ਜੇ ਬਖਸੇ ਤ ਗੁਰ ਵਡਿਆਈ ॥੨੫॥
Even if the Guru rebukes me, He still seems very sweet to me. And if He actually forgives me, that is the Guru's greatness. ||25||
But there's a provision for weak too ie Bhagat Jan can change Bhagwaan Ji's command
ਮੇਰੀ ਬਾਂਧੀ ਭਗਤੁ ਛਡਾਵੈ ਬਾਂਧੈ ਭਗਤੁ ਨ ਛੂਟੈ ਮੋਹਿ ॥
The devotee can release anyone from my bondage, but I cannot release anyone from his.
ਏਕ ਸਮੈ ਮੋ ਕਉ ਗਹਿ ਬਾਂਧੈ ਤਉ ਫੁਨਿ ਮੋ ਪੈ ਜਬਾਬੁ ਨ ਹੋਇ ॥੧॥
If, at any time, he grabs and binds me, even then, I cannot protest. ||1||
