Meditating with other people is even more powerful than meditating alone. It is likened to lighting a candle in a dark room. If we light one candle, it illuminates the room somewhat. If we light ten candles and group them near each other, the increase in light is magnified considerably. The power of people meditating in groups increases by the square of the number of people in the room. If there is one person, it has the power of one. If there are two people, it has the power of four. If there are 100 people, it has the power of 10,000! Studies have shown that groups of people meditating in cities for an entire weekend significantly lower the crime rate in those cities for that time period.
