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.
We can never know what strengths and revelations might be on the other side of our fears until we face them and feel them all the way through. True positive thinking is the mental stance of surrender, simply trusting the process. We learn to accept what is.
