A mandala is like a circle that represents a system of power in early Southeast Asia. Imagine a playground where everyone wants to be the king or queen. But there are so many kids who all want to be in charge! So, they form groups and try to make friends with other groups to make their group stronger.
In the mandala system, there were many kingdoms and rulers who wanted to be the most powerful, just like the kids on the playground. They formed alliances with other kingdoms and rulers to become stronger, but sometimes they also fought against each other.
Just like how on a playground, sometimes kids would team up with friends against other groups, but sometimes they would fight among themselves.
The mandala system was focused on gaining and maintaining power and influence, just like how the kids on the playground wanted to be in charge of everything.
