Practically everyone who has practiced silence finds that it improves concentration. . . .
Physiologically, deliberate silence calms the body. . . .
Psychologically, its benefit lies in the balance it offers. . . .
Spiritually, it puts us in touch with reality. It makes us far more aware of ourselves, both of our souls, and our bodies. Silence returns us to the present moment, that moment we are always trying to escape. Silence is also the other — often neglected — half of prayer. Prayer is a two-way conversation, so it must involve listening to God. And in order to listen, we must be silent. . . .
The regular and deliberate practice of silence also teaches us a great deal about the power and importance of words. . . . Keeping silence also helps us develop empathy.
