And now coming to the more scientific, metaphysical, explanation of silence. There is a certain amount of energy spent by words; and breath, which has to bring new life in the body, is hindered in its regular rhythm when man speaks all the time. It is not that a nervous person speaks too much, but much speaking makes him nervous. Where did the great power attained by Yogis and faqirs come from? It was gained by having learned and practiced the art of silence. And that is the reason why in the East, in the houses where faqirs meditated, and even at the court, there was silence.
