Meditation creates a safety net around a person's body, home, car, and office. As we continue daily meditation, we can see the expansion of this protective field. We are told that the protective aura of a Great One can even save a city from many disasters.
We must remember that we live in a sphere of many destructive forces, entities, microbes, and germs. It is only because of our aura that we can create a sphere of insulation around ourselves and protect ourselves from hostile forces. When we weaken our aura through wrong thinking, negative emotions, and wrong actions, we open doors for those forces that attack us.
