IN order to expound and describe this dark night, through which the soul passes in order to attain to the Divine light of the perfect union of the love of God, as far as is possible in this life, it would be necessary to have illumination of knowledge and experience other and far greater than mine; for this darkness and these trials, both spiritual and temporal, through which happy souls are wont to pass in order to be able to attain to this high estate of perfection, are so numerous and so profound that neither does human knowledge suffice for the understanding of them, nor experience for the description of them; for only he that passes this way can understand it, and even he cannot describe it.

2. Therefore, in order to say a little about this dark night, I shall trust neither to experience nor to knowledge, since both may fail and deceive; but, while not omitting to make such use as I can of these two things, I shall avail myself, in all that, with the Divine favour, I have to say, or at the least, in that which is most important and dark to the understanding, of Divine Scripture; for, if we guide ourselves by this, we shall be unable to stray, since He Who speaks therein is the Holy Spirit. And if aught I stray, whether through my imperfect understanding of that which is said in it or of matters uncollected with it, it is not my intention to depart from the sound sense and doctrine of our Holy Mother the Catholic Church; for in such a case I submit and resign myself wholly, not only to her command, but to whatever better judgment she may pronounce concerning it.

3. To this end I have been moved, not by any possibility that I see in myself of accomplishing so arduous a task, but by the confidence which I have in the Lord that He will help me to say something to relieve the great necessity which is experienced by many souls, who, when they set out upon the road of virtue, and Our Lord desires to bring them into this dark night that they may pass through it to Divine union, make no progress. At times this is because they have no desire to enter it or to allow themselves to be led into it; at other times, because they understand not themselves and lack competent and alert directors[70] who will guide them to the summit. And so it is sad to see many souls to whom God gives both aptitude and favour with which to make progress (and who, if they would take courage, could attain to this high estate), remaining in an elementary stage[71] of communion with God, for want of will, or knowledge, or because there is none who will lead them in the right path or teach them how to get away from these beginnings. And at length, although Our Lord grants them such favour as to make them to go onward without this hindrance or that, they arrive at their goal very much later, and with greater labour, yet with less merit, because they have not conformed themselves to God, and allowed themselves to be brought freely into the pure and sure road of union. For, although it is true that God is leading them, and that He can lead them without their own help, they will not allow themselves to be led; and thus they make less progress, because they resist Him Who is leading them, and they have less merit, because they apply not their will, and on this account they suffer more. For these are souls who, instead of committing themselves to God and making use of His help, rather hinder God by the indiscretion of their actions or by their resistance; like children who, when their mothers desire to carry them in their arms, start stamping and crying, and insist upon being allowed to walk, with the result that they can make no progress; and, if they advance at all, it is only at the pace of a child.

4. Wherefore, to the end that all, whether beginners or proficients, may know how to commit themselves to God's guidance, when His Majesty desires to lead them onward, we shall give instruction and counsel, by His help, so that they may be able to understand His will, or, at the least, allow Him to lead them. For some confessors and spiritual fathers, having no light and experience concerning these roads, are wont to hinder and harm such souls rather than to help them on the road; they are like the builders of Babel, who, when told to furnish suitable material, gave and applied other very different material, because they understood not the language, and thus nothing was done. Wherefore, it is a difficult and troublesome thing at such seasons for a soul not to understand itself or to find none who understands it. For it will come to pass that God will lead the soul by a most lofty path of dark contemplation and aridity, wherein it seems to be lost, and, being thus full of darkness and trials, constraints and temptations, will meet one who will speak to it like Job's comforters, and say that it is suffering from melancholy, or low spirits, or a morbid disposition, or that it may have some hidden sin, and that it is for this reason that God has forsaken it. Such comforters are wont to declare immediately that that soul must have been very evil, since such things as these are befalling it.

5. And there will likewise be those who tell the soul to retrace its steps, since it is finding no pleasure or consolation in the things of God as it did aforetime. And in this way they double the poor soul's trials; for it may well be that the greatest affliction which it is feeling is that of the knowledge of its own miseries, thinking that it sees itself, more clearly than daylight, to be full of evils and sins, for God gives it that light of knowledge in that night of contemplation, as we shall presently show. And, when the soul finds someone whose opinion agrees with its own, and who says that these things must be due to its own fault, its affliction and trouble increase infinitely and are wont to become more grievous than death. And, not content with this, such confessors, thinking that these things proceed from sin, make these souls go over their lives and cause them to make many general confessions, and crucify them afresh; not understanding that this may quite well not be the time for any of such things, and that their penitents should be left in the state of purgation which God gives them, and be comforted and encouraged to desire it until God be pleased to dispose otherwise; for until that time, no matter what the souls themselves may do and their confessors may say, there is no remedy for them.

6. This, with the Divine favour, we shall consider hereafter, and also how the soul should conduct itself at such a time, and how the confessor must treat it, and what signs there will be whereby it may be known if this is the purgation of the soul; and, in such case, whether it be of sense or of spirit (which is the dark night whereof we speak), and how it may be known if it be melancholy or some other imperfection with respect to sense or to spirit. For there may be some souls who will think, or whose confessors will think, that God is leading them along this road of the dark night of spiritual purgation, whereas they may possibly be suffering only from some of the imperfections aforementioned. And, again, there are many souls who think that they have no aptitude for prayer, when they have very much; and there are others who think that they have much when they have hardly any.

7. There are other souls who labour and weary themselves to a piteous extent, and yet go backward, seeking profit in that which is not profitable, but is rather a hindrance; and there are still others who, by remaining at rest and in quietness, continue to make great progress. There are others who are hindered and disturbed and make no progress, because of the very consolations and favours that God is granting them in order that they may make progress. And there are many other things on this road that befall those who follow it, both joys and afflictions and hopes and griefs: some proceeding from the spirit of perfection and others from imperfection. Of all these, with the Divine favour, we shall endeavour to say something, so that each soul who reads this may be able to see something of the road that he ought to follow, if he aspire to attain to the summit of this Mount.

8. And, since this introduction relates to the dark night through which the soul must go to God, let not the reader marvel if it seem to him somewhat dark also. This, I believe, will be so at the beginning when he begins to read; but, as he passes on, he will find himself understanding the first part better, since one part will explain another. And then, if he read it a second time, I believe it will seem clearer to him and the instruction will appear sounder. And if any persons find themselves disagreeing with this instruction, it will be due to my ignorance and poor style; for in itself the matter is good and of the first importance. But I think that, even were it written in a more excellent and perfect manner than it is, only the minority would profit by it, for we shall not here set down things that are very moral and delectable[72] for all spiritual persons who desire to travel toward God by pleasant and delectable ways, but solid and substantial instruction, as well suited to one kind of person as to another, if they desire to pass to the detachment of spirit which is here treated.

9. Nor is my principal intent to address all, but rather certain persons of our sacred Order of Mount Carmel of the primitive observance, both friars and nuns -- since they have desired me to do so -- to whom God is granting the favour of setting them on the road to this Mount; who, as they are already detached from the temporal things of this world, will better understand the instruction concerning detachment of spirit.
