That prayer has great power which a person makes with all his might. It makes a sour heart sweet, a sad heart merry, a poor heart rich, a foolish heart wise, a timid heart brave, a sick heart well, a blind heart full of sight, a cold heart ardent. It draws down the great God into the little heart; it drives the hungry soul up into the fullness of God; it brings together two lovers, God and the soul, in a wondrous place where they speak much of love.
