This question has been in my mind right since I am reciting bani . Mool mantar is the best example of saying what I want to say . ੴ ਸਤਿ ਨਾਮੁ ਕਰਤਾ ਪੁਰਖੁ ਨਿਰਭਉ ਨਿਰਵੈਰੁ ਅਕਾਲ ਮੂਰਤਿ ਅਜੂਨੀ ਸੈਭੰ ਗੁਰ ਪ੍ਰਸਾਦਿ || If we literally read mool mantar , it would be like :"EkOankar satinamu karta purakhu nirbhao nirvairu akaal murati ajooni saibhan gur prasadi . Note , that this is not how we read mool mantar . We recite it as "EkOankar satnam karta purakh nirbhao nirvair akaal murat ajooni saibhan gurprasad
