Rabbinic literature is like a really big library of books that Jewish leaders wrote a long time ago to help people understand and follow the Jewish religion. These books include stories, lessons, and explanations of how to live a good and moral life. They were written by special people called rabbis who were very wise and learned a lot about the Jewish religion. People study these books to learn about the Jewish faith and become better members of their community. It's like a big guide to help Jewish people understand what to do and how to be good people.
