“Mind over matter, people say. But what is matter, anyway? When you look at it under a microscope, it’s just tiny bits of stuff. Atomic particles. Subatomic particles. Look deeper and deeper and eventually you’ll find nothing. We’re mostly empty space. We’re mostly nothing. Tra-la-la. And we’re all the same nothingness. You and me, just filling the space with nothingness. We could walk through walls if we put our minds to it, people say. What they don’t mention is that walking through a wall would most likely kill you. Don’t forget that.”
