Now you have taken the knowledge from the library, but knowledge is just a word composed from an alphabet. GURU GRANTH is a book of knowledge under the banner named GOD so you think it is very precious and priceless. Nevertheless it is 99% social, pyscholgical evaluation and guidance. Only 1% is union with GOD and miracles. But the thing is, that in social activity is the give and take of karma. That plays a very big role in your life. The book is only for guidance. And it helps you by addiction. If you believe in anything enough, you can get God out of a rock (lover of God dhanna ji). And if you don’t then you can read all the books like Chattar Das (20 camels laden with books) and get nothing due to pride of knowledge.
