This is very obvious. And it can also make a big difference if we ponder it and take it in.
Every story was made up by someone.
And then passed on by others, and changed.
Any story was created by someone. Stories saying that a word means a certain thing. Or that something is good and something else is bad. Or that this is anger, or sadness, or pain, or joy. Or that loss or heartache is terrible. Or that humans are separate from rest of nature. Or that something called God or Spirit exist.
Stories about these stories were also made up by someone. Stories saying that the initial story is true, or false, or comes from an authority (so you should perceive and live as if it’s true), and so on.
Each of these stories were made up by someone. They are all a thought. They are more or less useful as a pointer in daily life. Their content is really a question only, a question about the world.
