Where does everything come from

From yourself. And I’ll prove it very simply. What is all of this? What you see, hear, feel, and think in this very moment, and nothing more. Only you could have created this, and no one else, for it is your eyes that see, your ears that hear, your body that feels, and your head that thinks. Others will see something different, for their eyes will be in a different place. And even if they behold the same thing, it will be a different head pondering it, and in that head everything is different.

Sometimes people also babble that there is a “world in general” that is the same for everyone. I’ll answer that. “The world in general” is a thought, and every head thinks it differently. So everything comes from within us anyway.
