You are simultaneously nothing and everything, the Alpha and the Omega, a universe within the Universe like an infinite matryoshka doll forever opening to reveal smaller and smaller versions of the self until, finally, you commence to splitting atoms with great bursts of energy in a nuclear fission of massive and creative destruction. You are pure energy moving outward through the Universe. Your body itself is made up of star stuff left over from the Big Bang with 99 percent of its mass comprised of just six common elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. The atoms that make up the very bones in your body, every striation of muscle tissue, every drop of blood, the billions of neurons in your brain, your beating heart—all of it was forged long ago in the crucible of the stars. Look up into the night sky. See where you came from, where you are going.
