I have only two questions 1. Is there a book about how, when you read, you will know about yourself better than we do? 2. What happens if we look at Allah's face directly in Jannah?

As for question number one: yes, the Quran and the Sunnah. As for question number two: you won't be given something that is more beloved to you than that. I ask Allah subhanahu wa ta'ala to make us and you from the people who gaze upon His face subhanahu wa ta'ala.
