He who has not God in himself cannot feel His absence. - Simone Weil, Gravity and Grace

"All the natural movements of the soul are controlled by laws analogous to those of physical gravity. Grace is the only exception. Grace fills empty spaces, but it can only enter where there is a void to receive it, and it is grace itself which makes this void. The imagination is continually at work filling up all the fissures through which grace might pass."
