In the East the great sages and saints sit quite still with lips closed for years. We call them muni, which means "one who takes the vow of silence." The person of today may think, "What a life: to be silent and do nothing." One does not know that some by their silence can do more than others talking for ten years could accomplish. A person may argue for months on a problem and not be able to explain it; another person with inner radiance may be able to answer the same thing in one moment.
