Four disciples of a Guru decide one day to observe seven days of silence. On the first day, all were silent and meditating, the day and night went peacefully. On second night, they did not have any light and fan in their room, the first disciple calls a servant to look in to the problem and make it all right for following days. The second disciple was surprised to hear the first talking and said, “We are not supposed to talk a word” The third one said, “You two are stupid, we have decided not to talk for seven days, so why did you talk?” The forth said, “I am the one who has not talked any thing”
