I speak of an "image", but it must not be supposed that one looks at it as at a painting; it is really alive, and sometimes even speaks to the soul and shows it things both great and secret. But you must realize that, although the soul sees this for a certain length of time, it can no more be gazing at it all the time than it could keep gazing at the sun. So the vision passes very quickly, though this is not because its brilliance hurts the interior sight -- that is, the medium by which all such things are seen -- as the brilliance of the sun hurts the eyes. When it is a question of exterior sight, I can say nothing about it, for the person I have mentioned, and of whom I can best speak, had not experienced this; and reason can testify only inadequately to things of which it has no experience. The brilliance of this vision is like that of infused light or of a sun covered with some material of the transparency of a diamond, if such a thing could be woven. This raiment looks like the finest cambric. Almost invariably the soul on which God bestows this favour remains in rapture, because its unworthiness cannot endure so terrible a sight.
