Yup, the thing is, like i said before when we bow down to the sri guru granth sahib, its not an act. Its hard for people who have less heart and understand in god to understand why we bow down. The words of god are in the guru granth sahib, so you should bow to it if you full understand and worship god. You see god is not seen, and god is when you surrender with no intention to change, but it automatically happens that you become god when you surrender. The guru granth sahib helps us to become of that of god.
Again, dont be to harsh if it says in sikhism not to worship idols. When we are bowing down to the guru granth sahib, we are not treating it as an idol of god. We are treating it as the first steps of being god-like. It is where we learn from god.
Its hard to understand, but, dont take everything to big in sikhism, when it says bow to the guru greanth sahib, first understand the meaning ot it, and understand what god is. People in sikhism sometimes do to much saying, this is not rite, thi sis wrong. Nothing is right and wrong, only when you know the meanings to everything then you will know.
sO DONT JUST SAY YOUR A SIKH BECAUSE YOU HAVE A TURBAN AND YOU FOLLOW THE GURU GRANTH SAHIB JI. You have to be so pure and so understand with the holy book and ultimatley with god.
