The deepest love cannot be boring. The vision of Beauty can never be dull. Finite experiences become commonplace, stale, flat, wearying, but never this one. If the mystic cannot find words to describe his enthrallment on earth, who is going to find words to speak of what eye has not seen nor ear heard? But babble on we must.
The weariness and eventual satiety that arise in extended sense pleasures are due to an overstimulation of an expendable (because material) power. Such overstimulation, however, is impossible in any purely intellectual activity because there is nothing expendable in it, and especially is it impossible in the purely intellectual activity of the beatific vision. Even on the natural level of everyday life the more one understands anything the more is his mind vigorous and strong. The intellect is not hurt by its light–it only grows in it. God seen cannot weaken our minds or weary them. Satiety never comes.
