Of course I do.
If it was in Gurmukhi I would still be missing important aspects.. As a student I would always strive to learn and never assume that I have learnt everything that my teacher is teaching me.. Otherwise they would cease being my teacher.
As a Sikh I believe that the pursuit of 'truth / Sat' is my duty.
If I am a sikh and have taken a 'teacher / Guru' (Guru Granth Sahib) then I as a true student and seeker of truth, I shouldn't be so arrogant as to think I have arrived at the truth.
if something is contradictory then by definition it is illogical. Which means I must question and seek the truth. It means I yet to fully understand what my guru is teaching me.
