We are not unique. We are not alone. Energy flows in and out of us. We must be willing to accept the energy of the world/universe. But we must also learn to give it back.  This energy has been here since the beginning.  It ran through our ancestors. It ran through every tree, rock, cloud, deer... maybe this is why so many cultures have a sacred energy of some sort i.e. a god, goddess, or just the energy itself.
