10.34.52   O Thou Light, which Tobias saw, when, these eyes closed, he taught his son the way of life; and himself went before with the feet of charity, never swerving. Or which Isaac saw, when his fleshly eyes being heavy and closed by old age, it was vouchsafed him, not knowingly, to bless his sons, but by blessing to know them. Or which Jacob saw, when he also, blind through great age, with illumined heart, in the persons of his sons shed light on the different races of the future people, in them foresignified; and laid his hands, mystically crossed, upon his grandchildren by Joseph, not as their father by his outward eye corrected them, but as himself inwardly discerned. This is the light, it is one, and all are one, who see and love it. But that corporeal light whereof I spake, it seasoneth the life of this world for her blind lovers, with an enticing and dangerous sweetness. But they who know how to praise Thee for it, "O all-creating Lord," take it up in Thy hymns, and are not taken up with it in their sleep. Such would I be. These seductions of the eyes I resist, lest my feet wherewith I walk upon Thy way be ensnared; and I lift up mine invisible eyes to Thee, that Thou wouldest pluck my feet out of the snare. Thou dost ever and anon pluck them out, for they are ensnared. Thou ceasest not to pluck them out, while I often entangle myself in the snares on all sides laid; because Thou that keepest Israel shalt neither slumber nor sleep.
