19. For just as thou art the utterly Real, thou alone dost fully know, since thou art immutably, and thou knowest immutably, and thou willest immutably. And thy Essence knows and wills immutably. Thy Knowledge is and wills immutably. Thy Will is and knows immutably. And it does not seem right to thee that the immutable Light should be known by the enlightened but mutable creature in the same way as it knows itself. Therefore, to thee my soul is as a land where no water is; for, just as it cannot enlighten itself by itself, so it cannot satisfy itself by itself. Thus the fountain of life is with thee, and "in thy light shall we see light."
