Prayer is naught else but a yearning of the soul... When it is practiced with the whole heart, it has great power. It makes a sour heart sweet, a sad heart merry, a poor heart rich, a foolish heart wise, a timid heart courageous, a sick heart well, a blind heart full of vision, a cold heart ardent. For it draws down the great God into the little heart; it drives the hungry soul up to the plentitude of God; it brings together these two lovers, God and the soul, in a wondrous place where they speak much of love.
How terribly the rice suffers under the pestle!
But it emerges polished, as white as cotton.
The same process tempers the human spirit:
Hard trials shape us into polished diamonds.
