15. This vision is to be esteemed very highly; nor is there, in my opinion, any risk in it, because the fruits of it show that the devil has no power here. I think he tried three or four times to represent our Lord to me, in this way, by a false image of Him. He takes the appearance of flesh, but he cannot counterfeit the glory which it has when the vision is from God. Satan makes his representations in order to undo the true vision which the soul has had: but the soul resists instinctively; is troubled, disgusted, and restless; it loses that devotion and joy it previously had, and cannot pray at all. In the beginning, it so happened to me three or four times. These satanic visions are very different things; and even he who shall have attained to the prayer of quiet only will, I believe, detect them by those results of them which I described when I was speaking of locutions. [10] They are most easily recognised; and if a soul consents not to its own delusion, I do not think that Satan will be able to deceive it, provided it walks in humility and singleness of heart. He who shall have had the true vision, coming from God, detects the false visions at once; for, though they begin with a certain sweetness and joy, the soul rejects them of itself; and the joy which Satan ministers must be, I think, very different--it shows no traces of pure and holy love: Satan very quickly betrays himself. 16. Thus, then, as I believe, Satan can do no harm to anyone who has had experience of these things; for it is the most impossible of all impossible things that all this may be the work of the imagination. There is no ground whatever for the supposition; for the very beauty and whiteness of one of our Lord's Hands [11] are beyond our imagination altogether. How is it that we see present before us, in a moment, what we do not remember, what we have never thought of, and, moreover, what, in a long space of time, the imagination could not compass, because, as I have just said, [12] it far transcends anything we can comprehend in this life? This, then, is not possible. Whether we have any power in the matter or not will appear by what I am now going to say.
