Wherever the Word is to be heard, it must occur in the stillness and in silence... There we can hear it and understand it correctly, in that state of unknowing. Where we know nothing, it becomes apparent and reveals Itself... People should be as free of their own knowledge as when they were not yet, letting God accomplish what God wills ... standing empty.
Take great care to restrain your tongue and be circumspect. Let only discretion and charity open your mouth. And practice the advice of all the Saints to break silence only with words that are worth more than silence. Silence is one of the most certain signs that God dwells in a soul.
