Everything in the Universe is vibrating. This is no theory, it is a fact. The entire Universe is nothing but vibrations. The good vibrations make us happy, the unwholesome vibrations cause misery. Vipassana will help you come out of effect of bad vibrations- the vibrations caused by a mind full of craving and aversion. When the mind is perfectly balanced, the vibrations become good. And these good or bad vibrations you generate start influencing the atmosphere all around you.
