Okay kiddo, so you know how when we read a storybook, sometimes we might not understand everything that's happening or why the characters are doing certain things?
Well, imagine that there was another book that you could read along with the storybook that would explain everything! That's what atthakatha is.
Atthakatha is like a big, long book that helps people understand the stories that are told in another big book called the Tipitaka. The Tipitaka is a very important book in Buddhism that has lots of stories and teachings about how to live a good life, be kind to others, and find inner peace.
But, sometimes it can be hard for people to understand all of the things that are being said in the Tipitaka. That's where atthakatha comes in. Atthakatha is like a big guide that helps people understand what the stories mean, why certain things are happening, and how to use the teachings in their everyday life.
So, it's kind of like having a teacher or a friend who helps you understand things that might seem confusing at first. And just like how we can learn a lot from our teachers and friends, people can learn a lot from atthakatha too!
