what i have yet to understand as per your understanding of Waheguru Simran is that how come the word wahguru only comes 3-4 times in gurbani? And wahguru was not even said by guru sahibs, it was said by bhats, who called guru wah. meaning wah guru. from where did you get that this is naam.
Secondly if you look at Bhai gurdas deeya vaaran, first he says
Wahguru gurmantar hai jaap humai kohi.
And then later on he says
Trigjeeva gur shabad bin hor mantar simranee.
how can these two lines contradict each other. first he says waheguru is gurmantar, and then he says the only mantar is guru shabad and he says there is no other mantar.
An on the topic of gurbani viyakarn, Prof sahib singh teeka is panth parvanth, he has also said that i am not perfect and gurbani could go on and on, it is very deep, dont take my aarth as the last.
No need to give names S Singh knows what i am talking about, when the teeka of prof sahib singh has been used through any argument it is that teeka which should only be used because there is consencisis on his status in the panth. However when it comes down to not agreeing with one of his points they switch to another teeka which argues there point.
