As I read your question, I saw the answer contained within it. You said you love to read the Siri Guru Granth Sahib. And why? The next sentence tells it all. Because you "feel that God is within you". That is the transformative holy technology of the Siri Guru Granth Sahib. Just keep reading, mistakes and all, Guru will cover for you and you will find yourself reading more accurately and understanding more completely what Guru is telling you. You will find that different words of wisdom will come into your mind as you go through your normal daily life. You will say" Ahh! That's what the Guru meant! I see it now." And you will change from thoughts and behavior that does not serve the God within you, to those thoughts and behaviors that bring out the God within to share with all.
