Hello Sir, I have studied Buddhism from books/school when i was small. However we don't have a book with us after we have studied it. It never forced us to do anything. Merely a guide. To take what's in it is up to us. No one from the divine has written those, it was all Buddha's teachings which he went and found.
"No one saves us but ourselves. No one can and no one may. We ourselves must walk the path" - Gautama Buddha
