Okay kiddo, have you ever heard of a story? Well, avadana is a kind of story that people from long ago used to tell to teach others about good behavior and morals. They were like fairy tales, but instead of magic and giants, they had real people doing good, kind things.
People often told these stories to help others learn about how to be better people. The stories might be about someone who was really honest or someone who was super generous. They might even be about animals!
One important thing about avadanas is that they were written in a special language called Sanskrit. This language was used by people in India a very long time ago. But don't worry, you don't need to know Sanskrit to understand avadanas now! They have been translated into many different languages so anyone can read them.
So that's what avadanas are, little stories to help people learn how to be the best they can be. And they can still teach us those same lessons today!
