For, however dark a night may be, something can always be seen, but in true darkness nothing can be seen; and thus in the night of sense there still remains some light, for the understanding and reason remain, and are not blinded. But this spiritual night, which is faith, deprives the soul of everything, both as to understanding and as to sense. And for this cause the soul in this night says that it was journeying ‘in darkness and secure,’ which it said not in the other.
