Frutto del silenzio è la preghiera.

When you pray, do not be similar to the hypocrites who love to pray standing upright in the synagogues and in the corners of the squares, to be seen by men. Truly I tell you, they have already received their reward. On the other hand, when you pray, enter your room and, closing the door, pray to your Father in secret; and your Father, who sees in secret, will reward you.
(Jesus of Nazareth)

The fruit of silence is prayer. The fruit of prayer is faith. The fruit of faith is love. The fruit of love is serving.
(Mother Teresa of Calcutta)
