How do you explain the inexplicable?
You don't.
You might try and try and try and try and try, but sometimes a thing cannot be explained. Sometimes not even to yourself.
So instead, you demonstrate it, at every possible opportunity, and you hope with all your heart that eventually it's understood before you die.
Although that can be kind of tough, because sometimes you died a long time ago, and you're just too fucking stubborn to admit it.
