I have often reminded you, my dear sister, about the remembrance of God, and now I tell you again: unless you work and sweat to impress on your heart and mind this awe-inspiring Name, you keep silence in vain, you sing in vain, you fast in vain, you watch in vain. In short, all a nun’s work will be useless without this activity, without recollection of God.
This is the beginning of silence for the Lord’s sake, and it is also the end. This most desirable Name is the soul of stillness and silence. By calling it to mind we gain joy and gladness, forgiveness of sins and a wealth of virtues. Few have been able to find this most glorious Name, save only in stillness and silence. Man can attain it in no other way, even with great effort. Therefore, knowing the power of this advice, I entreat you for the love of Christ always to be still and silent, since these virtues enrich remembrance of God within us.
