Energy, like circles spreading through the water from a thrown stone, spreads from each person to the entire outer space and returns to it, amplified many times over. The quality of energy is key when you're laughing at you, the whole world is laughing at you, and your anger will come back and leave a rough slap on your face. Changes in one energy field lead to changes in the general, we are all connected, even the smallest positive changes are important, even thoughts are important. You and you alone are the reason for everything that happens to you, and each of us must be the change we want to see in the world.
