Hold your hands up, palms facing each other, one beside each ear. Feel the heat radiating from your head, and get a sense of how small the space is between your hands. It’s not much bigger than a basketball.
Every single thing you’ve ever experienced, every sour memory, every embarrassment, every triumph, every great fear and every great hope, is confined within the space between your hands. All conceptions or visions of your past and future are right there floating above your neck, and they cannot be found anywhere else. They have no weight of their own, no permanence. They can take no form other than that of a fleeting thought."
