Twentieth-century Quaker Thomas Kelly wrote:
Over the margins of life comes a whisper, a faint call, a premonition of richer living which we know we are passing by. We have hints that there is a way of life vastly richer and deeper than all this hurried existence, a life of unhurried serenity and peace and power. If only we could slip over into that Center! If only we could find the Silence which is the source of sound!
