Knowledge is therefore quick in purifying, and fit for that acceptable transformation to the better. Whence also with ease it removes [the soul] to what is akin to the soul, divine and holy, and by its own light conveys man through the mystic stages of advancement; till it restores the pure in heart to the crowning place of rest; teaching to gaze on God, face to face, with knowledge and comprehension. For in this consists the perfection of the gnostic soul, in its being with the Lord, where it is in immediate subjection to Him, after rising above all purification and service.
