A void of information in the void
When you miss someone, observe where exactly this "missing" is. Is it in your heart? In your mind? In which part of your brain? In which cell? Is it in the left or right side of your brain? In which part of your body?
Finally, you will observe that this "missing" is nowhere to be found. It is empty, just a void of information in the void. This void of information controls our brains and our behavior.
