Okay kiddo, imagine you have a toy box. Inside your toy box, there are lots of different toys, like dolls, cars, and balls. Now, let's say you want to sort your toys into different groups based on what they're made of. You might put all the wooden toys in one group, and all the plastic toys in another group.
In Buddhism, there are also different groups or schools of thought, and Svatantrika is one of them. Just like sorting your toys, the people who follow this school of thought have different ways of thinking about things than other schools.
Svatantrika means "autonomous" or "independent" in Sanskrit. So the people who follow Svatantrika believe that things can have their own existence, independent of other things. They also believe that things can be empty or have no inherent existence, but this emptiness is not separate from the thing itself.
To give you an example, imagine a tree. The tree exists independently of other things, but it is also made up of different parts, like the trunk, branches, and leaves. And yet, even though the tree is made up of these parts, it is still one whole thing. That's kind of like how the Svatantrika thinkers see emptiness and existence.
So, Svatantrika is just one way of thinking about the world in Buddhism. Everyone has different ideas and ways of thinking, just like you might sort your toys in different ways.
