"What measures, then, shall we adopt? What machine employ, or what reason consult by means of which we may contemplate this ineffable beauty; a beauty abiding in the most divine sanctuary without ever proceeding from its sacred retreats lest it should be beheld by the profane and vulgar eye? We must enter deep into ourselves, and, leaving behind the objects of corporeal sight, no longer look back after any of the accustomed spectacles of sense. For, it is necessary that whoever beholds this beauty, should withdraw his view from the fairest corporeal forms; and, convinced that these are nothing more than images, vestiges and shadows of beauty, should eagerly soar to the fair original from which they are derived. For he who rushes to these lower beauties, as if grasping realities, when they are only like beautiful images appearing in water, will, doubtless, like him in the fable, by stretching after the shadow, sink into the lake and disappear. For, by thus embracing and adhering to corporeal forms, he is precipitated, not so much in his body as in his soul, into profound and horrid darkness; and thus blind, like those in the infernal regions, converses only with phantoms, deprived of the perception of what is real and true."
