Imagine you have a big puzzle with lots of pieces. Each piece of the puzzle is important, but when you put them all together, you get a bigger picture.
Huayan is a type of Buddhism. It's like a set of rules and ideas that people use to help them understand the world and how to live a good life. Huayan is based on the idea that everything in the universe is connected to everything else, like how each puzzle piece is connected to the other pieces.
Huayan also talks a lot about how things can seem different depending on how you look at them. For example, if you look at a tree from one angle, it might look very different from if you look at it from another angle. This idea is important in huayan because it helps people understand that things might seem different or confusing, but they are all connected in some way.
Another important idea in huayan is called "interpenetration." This means that everything in the universe is connected and can affect each other. For example, if you throw a pebble into a pond, it will make ripples that affect everything around it. The idea of interpenetration is similar to how each puzzle piece affects the other pieces around it.
So, huayan is a type of Buddhism that helps people understand the world and how to live a good life. It teaches that everything in the universe is connected, and that things can seem different depending on how you look at them. And it also talks about how everything can affect each other, just like how each puzzle piece affects the other pieces around it.
