The universe is something like a powerful radar system that is set up from all sides to record every action and every event that may take place anywhere, even of the least intensity or momentum. Meditation, when it is properly done, is not a silent and non-interfering process of thinking by some individual in some undisturbed corner, but a positive interference with the very structure of the universe and, sometimes, a directly employed system starts working at once and the forces around receive a warning, as it were, that someone is in a state of meditation. Immediately, counter-forces are gathered by what is generally known as the lower nature and the meditation receives a setback.
