PROLOGUE
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 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 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.
