Ascent of Mount Carmel/Book 3/Chapter X
CHAPTER X
Of the third evil that may come to the soul from the devil, through the imaginary apprehensions of the memory.
From all that has been said above it may be clearly understood and inferred how great is the evil that may come to the soul from the devil by way of these supernatural apprehensions. For not only can he represent to the memory and the fancy many false forms and ideas, which seem true and good, impressing them on spirit and sense with great effectiveness and certifying them to be true by means of suggestion (so that it appears to the soul that it cannot be otherwise, but that everything is even as he represents it; for, as he transfigures himself into an angel of light, he appears as light to the soul); but he may also tempt the soul in many ways with respect to true knowledge, which is of God, moving its desires and affections, whether spiritual or sensual, in unruly fashion with respect to these; for, if the soul takes pleasure in such apprehensions, it is very easy for the devil to cause its desires and affections to grow within it, and to make it fall into spiritual gluttony and other evils.
2. And, in order the better to do this, he is wont to suggest and give pleasure, sweetness and delight to the senses with respect to these same things of God, so that the soul is corrupted and bewildered[1] by that sweetness, and is thus blinded with that pleasure and sets its eyes on pleasure rather than on love (or, at least, very much more than upon love), and gives more heed to the apprehensions than to the detachment and emptiness which are found in faith and hope and love of God. And from this he may go on gradually to deceive the soul and cause it to believe his falsehoods with great facility. For to the soul that is blind falsehood no longer appears to be falsehood, nor does evil appear to be evil, etc.; for darkness appears to be light, and light, darkness; and hence that soul comes to commit a thousand foolish errors, whether with respect to natural things, or to moral things, or to spiritual things; so that that which was wine to it becomes vinegar. All this happens to the soul because it began not, first of all, by denying itself the pleasure of those supernatural things. At first this is a small matter, and not very harmful, and the soul has therefore no misgivings, and allows it to continue, and it grows, like the grain of mustard seed, into a tall tree. For a small error at the beginning, as they say, becomes a great error in the end.
3. Wherefore, in order to flee from this great evil, which comes from the devil, the soul must not desire to have any pleasure in such things, because such pleasure will most surely lead it to become blind and to fall. For of their own nature, and without the help of the devil, pleasure and delight and sweetness blinds the soul. And this was the meaning of David when he said: ‘Perhaps darkness shall blind me in my delights and I shall have the night for my light.’[2]
