Okay kiddo, so you know how when you read a book or a story, it's usually divided into chapters? Well, sometimes there's a shorter book or booklet that talks about a specific topic, like a religious or political idea, and it's usually called a tract.
Think of it like a tiny chapter, but instead of being part of a bigger story, it's a little book on its own. These tracts can be used to spread information or a particular viewpoint, like explaining why someone should believe in a certain religion or why they should vote for a certain candidate.
So just like how each chapter helps tell the whole story, a tract can help people understand a certain idea or belief. Does that make sense to you, little one?
