Okay, so imagine you have two different books in front of you. One of them is called "atthakavagga" and the other is called "parayanavagga". They are both parts of a bigger book called the "Sutta Nipata".
The atthakavagga talks about different teachings and stories that Buddha shared with his followers. It's all about learning how to be a good person, by being kind to others, being honest, and not being selfish. It's kind of like a guidebook for how to live a good life.
The parayanavagga, on the other hand, talks about things like death and the afterlife. It can be a bit scary, but it's important to talk about these things because they help us understand that life is precious and we should make the most of the time we have.
So, even though these two books are different, they both have important messages for us to learn from. And by reading both of them, we can become better people and learn more about the world around us.
