GYANI JARNAIL SINGH Ji,
I appreciate your view of using the grammer in interpretation of Gurbaani.
As a matter of fact grammer gives specific direction to the meaning of the Gurbaani words.
If there is WILL to understand Gurbaani Grammer it is very SIMPLE.If there is no WILL then it is most difficult.So it depends on our acceptance of grammer in Gurbaani.
I have my personal experience that most of the people think that there is no role of grammer in Gurbaani understanding.
So in these circumstances what best can be done you may think of some modus operandi to convince the people about the significance of understanding of Gurbaani as per grammer.

I hope you will look into this.
