At a certain pitch of religious experience, the heart just wants to sing; it breaks into song. Paradoxically, you could say when silence finds its fullness, it comes to word. As the Book of Wisdom says, "When night in its swift course had reached its halfway point and deep silence embraced everything" -- when night was at its darkest and deepest -- there "the eternal Word leaped from the Heavenly throne": silence burst into song.
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.
