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.

~ Mechthild of Magdeburg in THE HIDDEN TRADITION by Lavinia Byrne
