Energy healing can be sent anywhere because it is energy, and energy is not limited by time or distance.
How is this possible? Because we're are all connected by energy. This is a phenomenon called "Nonlocality. If this is hard to wrap your mind around, you're not alone. It's quantum physics.
Current scientific studies are proving this, which boggles the mind of scientists. Yet, as much as they try, they can't dispute it. Einstein knew this, and he called it "Spooky action at a distance." The Spooky Action Phenomenon was recently featured on NPR's "Science Friday": http://www.sciencefriday.com/segments/in-the-quantum-world-physics-gets-philosophical/
"Over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time. The phenomenon of nonlocality-the ability of two particles to act in harmony across the vastness of space-appears to be almost magical. More recently, the mystery has deepened as other forms of nonlocality have turned up. This strange occurrence...holds the potential to undermine our most basic understanding of physical reality. If space isn't what we thought it was, then what is it?" http://spookyactionbook.com
What does Nonlocality mean? It means when you take action on a particle in one part of the planet, the particle in another part demonstrates an identical response. Just like those particles, when energy therapists channel healing energy, they can send it to another person in another part of the world, and the person will receive the healing energy at the exact same moment. That's Non-Locality. It means that the two don't have to be in the same location to influence each other energetically.
