I have followed the thread very closely.
It appears to me that no one has read the question in the context Of which it has been put into.

Let us see that has been posed as a question.

"One is faced with a peculiar situation. In case there is a suggestion by the objector the same can be looked into by the person who is posting.However, where the person claiming something to be Not as per Gurmat does not give any considered reason ,how and who will be the person or an authority who will decide that the matter is as per gurmat or not.The person may start creating nuisance claiming a person possessed with superior knowledge."

Mr. hps has very clearly stated the matter so faras the interpretation of the bani and this post is concerned oin the site if one member makes a nuisance in the thread. I see also that there is some thread about ' need guidance in interpretation....." where one surinder kaur cheema ji has been poking herself as a person of great knowledge.It is in this context that the question probably was posed.She had stated something as going against the 'gurmat' and on being asked had not responded.

It may be further be observed that it is in this forum itself some person want to establish monoploy ,then the problem arises.




Thus for me 'WAHEGURU' Is not a GOD? He should be, if HE is, always next and inferior to Ek Onkar ,Sat Naam ,Karta Purukh, Nirbhau, NIrver , akalmurut ajuni Saibhung.........,..'''


Regarding the above it can be clarified that waheguru is not a physical God, it is probably the one of the name of the God. There is no doubt that waheguru 'gurumanter' is not a part of approved bani so far and hence a very tricky question.
It is as per my understanding.You may kindly like to opine as well.

It is also suggested that one should stop monopolising the areas Of interpretation else this site is likely to suffer as well.I am not likely to visit the site again.It is full of egotistic write ups.
