The tongue is a small member, but it does big things. A religious who does not keep silence will never attain holiness; that is, she will never become a saint. Let her not delude herself - unless it is the Spirit of God who is speaking through her, for then she must not keep silent. But, in order to hear the voice of God, one has to have silence in one's soul and to keep silence; not a gloomy silence but an interior silence; that is to say, recollection in God.
Mary Faustina KowalskaHe who wants to learn true humility should reflect upon the Passion of Jesus. (267)
Mary Faustina KowalskaA talkative soul lacks both the essential virtues and intimacy with God. A deeper interior life, one of gentle peace and of that silence where the Lord dwells, is quite out of the question. A soul that has never tasted the sweetness of inner silence is a restless spirit which disturbs the silence of others.
