This trend may be growing because we do not have easy access to actual wording on display so that each one can sing along. Waheguru chanting is easy/ well known and promotes participation.
We can have similar lines, like.... Sagal bẖavan ke nā▫ikā ik cẖẖin ḏaras ḏikẖā▫e jī.....
There are all great wording in Sri Guru Granth Sahib Ji but only a few are known/ understood by people.
By the way, I did a mistake first when I was writing the shabad line above! and how do we know that we are correct?Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/showthread.php?t=34755
My point is that we should get participation first
and then just try to correct them. If we insist on correctness first then we will not have any student and these students, in search of some religiosity, would turn to hinduism or elsewhere.
You may say that we do not want to compete and compromise just to have more people..... usual quality vs. quantity argument!
When you have less and less people, it turns out to be a cult because lesser number of people will dictate terms and benefit of more brains helping to find the best is lost.
I agree that it is not a marketing... it is religion but you can not say that I do not like this person because he is not singing it correctly. He is a follower in his own sense. He is singing it with full devotion and that is a qualifying degree he has. How he does it... is a matter of opinion. Religion is inclusive.
A controversial example: Harbhajan singh Yogi.... No one outside India/sikhs would have known sikhism otherwise. Even now not many come to Gurudwara except born sikhs.
We do not force/ we do not have a mission to marry girls of other religion to make them sikhs. We welcome voluntary visitors .. in such a situation we have to invent ways to spread our message in easy language with less restrictive rules.
Each brain is different and responds in different way. We can not have only one CORRECT way for all.
Sorry for my language..... I should be more polite. I feel that it is ok but many feel it other way..... each one is different. Correct way seems to be what society ACCEPTS as right at this time. Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/showthread.php?t=34755
Another example: in 1897, the committee agreed that a particular form of Dasam Granth is authentic but now we have different view.
Nothing is wrong... it is just different! ( as long as it is not causing deaths physical or mental)
