BEFORE passing on, I want you to consider what will be the state of this castle, so beautiful and resplendent this Orient pearl, this tree of life, planted in the living waters of life28 -- namely, in God -- when the soul falls into a mortal sin. No thicker darkness exists, and there is nothing dark and black which is not much less so than this. You need know only one thing about it -- that, although the Sun Himself, Who has given it all its splendour and beauty, is still there in the centre of the soul, it is as if He were not there for any participation which the soul has in Him, though it is as capable of enjoying Him as is the crystal of reflecting the sun. While in a state like this the soul will find profit in nothing, and hence, being as it is in mortal sin, none of the good works it may do will be of any avail29 to win it glory; for they will not have their origin in that First Principle, which is God, through Whom alone our virtue is true virtue. And, since this soul has separated itself from Him, it cannot be pleasing in His eyes; for, after all, the intention of a person who commits a mortal sin is not to please Him but to give pleasure to the devil; and, as the devil is darkness itself, the poor soul becomes darkness itself likewise.
