A person must learn to be alone in solitude, to listen in one's heart to the wordless speech of the Spirit, and to discover the truth bout oneself and God. Then their word to others will be a word of power, because it is a word of silence.
I remember years ago in Korea in the Peace Corps, how I felt the first time I partook of the daily culture of "just sitting" together with friends in informal tearooms in Seoul, without saying a word; at first I felt quite nervous and bored, but when I was able to relax my mind and just be, it was a refreshing communion... each moment's meeting of a person or even a flower is precious and fleeting, it is to be savored completely, perhaps best in silence.
