Somewhat reluctantly, out of respect for a venerable tradition, we publish the Dark Night as a separate treatise, though in reality it is a continuation of the Ascent of Mount Carmel and fulfils the undertakings given in it:

The first night or purgation is of the sensual part of the soul, which is treated in the present stanza, and will be treated in the first part of this book. And the second is of the spiritual part; of this speaks the second stanza, which follows; and of this we shall treat likewise, in the second and the third part, with respect to the activity of the soul; and in the fourth part, with respect to its passivity.[Ascent of Mount Carmel, Book I, chapter I, section 2.]

This “fourth part” is the Dark Night. Of it the Saint writes in a passage which follows that just quoted:

And the second night, or purification, pertains to those who are already proficient, occurring at the time when God desires to bring them to the state of union with God. And this latter night is a more obscure and dark and terrible purgation, as we shall say afterwards.

In his three earlier books he has written of the Active Night, of Sense and of Spirit; he now proposes to deal with the Passive Night, in the same order. He has already taught us how we are to deny and purify ourselves with the ordinary help of grace, in order to prepare our senses and faculties for union with God through love. He now proceeds to explain, with an arresting freshness, how these same senses and faculties are purged and purified by God with a view to the same end—that of union. The combined description of the two nights completes the presentation of active and passive purgation, to which the Saint limits himself in these treatises, although the subject of the stanzas which he is glossing is a much wider one, comprising the whole of the mystical life and ending only with the Divine embraces of the soul transformed in God through love.

The stanzas expounded by the Saint are taken from the same poem in the two treatises. The commentary upon the second, however, is very different from that upon the first, for it assumes a much more advanced state of development. The Active Night has left the senses and faculties well prepared, though not completely prepared, for the reception of Divine influences and illuminations in greater abundance than before. The Saint here postulates a principle of dogmatic theology—that by himself, and with the ordinary aid of grace, man cannot attain to that degree of purgation which is essential to his transformation in God. He needs Divine aid more abundantly. “However greatly the soul itself labours,” writes the Saint, “it cannot actively purify itself so as to be in the least degree prepared for the Divine union of perfection of love, if God takes not its hand and purges it not in that dark fire.”

The Passive Nights, in which it is God Who accomplishes the purgation, are based upon this incapacity. Souls “begin to enter” this dark night

when God draws them forth from the state of beginners—which is the state of those that meditate on the spiritual road—and begins to set them in the state of progressives—which is that of those who are already contemplatives—to the end that, after passing through it, they may arrive at the state of the perfect, which is that of the Divine union of the soul with God.

Before explaining the nature and effects of this Passive Night, the Saint touches, in passing, upon certain imperfections found in those who are about to enter it and which it removes by the process of purgation. Such travellers are still untried proficients, who have not yet acquired mature habits of spirituality and who therefore still conduct themselves as children. The imperfections are examined one by one, following the order of the seven deadly sins, in chapters (II–VIII) which once more reveal the author’s skill as a director of souls. They are easy chapters to understand, and of great practical utility, comparable to those in the first book of the Ascent which deal with the active purgation of the desires of sense.

In Chapter VIII, St. John of the Cross begins to describe the Passive Night of the senses, the principal aim of which is the purgation or stripping of the soul of its imperfections and the preparation of it for fruitive union. The Passive Night of Sense, we are told, is “common” and “comes to many,” whereas that of Spirit “is the portion of very few.” The one is “bitter and terrible” but “the second bears no comparison with it,” for it is “horrible and awful to the spirit.” A good deal of literature on the former Night existed in the time of St. John of the Cross and he therefore promises to be brief in his treatment of it. Of the latter, on the other hand, he will “treat more fully… since very little has been said of this, either in speech or in writing, and very little is known of it, even by experience.”

Having described this Passive Night of Sense in Chapter VIII, he explains with great insight and discernment how it may be recognized whether any given aridity is a result of this Night or whether it comes from sins or imperfections, or from frailty or lukewarmness of spirit, or even from indisposition or “humours” of the body. The Saint is particularly effective here, and we may once more compare this chapter with a similar one in the Ascent (II, XIII)—that in which he fixes the point where the soul may abandon discursive meditation and enter the contemplation which belongs to loving and simple faith.

Both these chapters have contributed to the reputation of St. John of the Cross as a consummate spiritual master. And this not only for the objective value of his observations, but because, even in spite of himself, he betrays the sublimity of his own mystical experiences. Once more, too, we may admire the crystalline transparency of his teaching and the precision of the phrases in which he clothes it. To judge by his language alone, one might suppose at times that he is speaking of mathematical, rather than of spiritual operations.

In Chapter X, the Saint describes the discipline which the soul in this Dark Night must impose upon itself; this, as might be logically deduced from the Ascent, consists in “allowing the soul to remain in peace and quietness,” content “with a peaceful and loving attentiveness toward God.” Before long it will experience enkindlings of love (Chapter XI), which will serve to purify its sins and imperfections and draw it gradually nearer to God; we have here, as it were, so many stages of the ascent of the Mount on whose summit the soul attains to transforming union. Chapters XII and XIII detail with great exactness the benefits that the soul receives from this aridity, while Chapter XIV briefly expounds the last line of the first stanza and brings to an end what the Saint desires to say with respect to the first Passive Night.

At only slightly greater length St. John of the Cross describes the Passive Night of the Spirit, which is at once more afflictive and more painful than those which have preceded it. This, nevertheless, is the Dark Night par excellence, of which the Saint speaks in these words: “The night which we have called that of sense may and should be called a kind of correction and restraint of the desire rather than purgation. The reason is that all the imperfections and disorders of the sensual part have their strength and root in the spirit, where all habits, both good and bad, are brought into subjection, and thus, until these are purged, the rebellions and depravities of sense cannot be purged thoroughly.”

Spiritual persons, we are told, do not enter the second night immediately after leaving the first; on the contrary, they generally pass a long time, even years, before doing so, for they still have many imperfections, both habitual and actual (Chapter II). After a brief introduction (Chapter III), the Saint describes with some fullness the nature of this spiritual purgation or dark contemplation referred to in the first stanza of his poem and the varieties of pain and affliction caused by it, whether in the soul or in its faculties (Chapters IV–VIII). These chapters are brilliant beyond all description; in them we seem to reach the culminating point of their author’s mystical experience; any excerpt from them would do them an injustice. It must suffice to say that St. John of the Cross seldom again touches those same heights of sublimity.

Chapter IX describes how, although these purgations seem to blind the spirit, they do so only to enlighten it again with a brighter and intenser light, which it is preparing itself to receive with greater abundance. The following chapter makes the comparison between spiritual purgation and the log of wood which gradually becomes transformed through being immersed in fire and at last takes on the fire’s own properties. The force with which the familiar similitude is driven home impresses indelibly upon the mind the fundamental concept of this most sublime of all purgations. Marvellous, indeed, are its effects, from the first enkindlings and burnings of Divine love, which are greater beyond comparison than those produced by the Night of Sense, the one being as different from the other as is the body from the soul. “For this (latter) is an enkindling of spiritual love in the soul, which, in the midst of these dark confines, feels itself to be keenly and sharply wounded in strong Divine love, and to have a certain realization and foretaste of God.” No less wonderful are the effects of the powerful Divine illumination which from time to time enfolds the soul in the splendours of glory. When the effects of the light that wounds and yet illumines are combined with those of the enkindlement that melts the soul with its heat, the delights experienced are so great as to be ineffable.

The second line of the first stanza of the poem is expounded in three admirable chapters (XI-XIII), while one short chapter (XIV) suffices for the three lines remaining. We then embark upon the second stanza, which describes the soul’s security in the Dark Night—due, among other reasons, to its being freed “not only from itself, but likewise from its other enemies, which are the world and the devil.”

This contemplation is not only dark, but also secret (Chapter XVII), and in Chapter XVIII is compared to the “staircase” of the poem. This comparison suggests to the Saint an exposition (Chapters XVIII, XIX) of the ten steps or degrees of love which comprise St. Bernard’s mystical ladder. Chapter XXI describes the soul’s “disguise,” from which the book passes on (Chapters XXII, XXIII) to extol the “happy chance” which led it to journey “in darkness and concealment” from its enemies, both without and within.

Chapter XXIV glosses the last line of the second stanza—“my house being now at rest.” Both the higher and the lower “portions of the soul” are now tranquilized and prepared for the desired union with the Spouse, a union which is the subject that the Saint proposed to treat in his commentary on the five remaining stanzas. As far as we know, this commentary was never written. We have only the briefest outline of what was to have been covered in the third, in which, following the same effective metaphor of night, the Saint describes the excellent properties of the spiritual night of infused contemplation, through which the soul journeys with no other guide or support, either outward or inward, than the Divine love “which burned in my heart.”

It is difficult to express adequately the sense of loss that one feels at the premature truncation of this eloquent treatise. We have already given our opinion[In his introduction to Ascent of Mount Carmel.] upon the commentaries thought to have been written on the final stanzas of the “Dark Night.” Did we possess them, they would explain the birth of the light—“dawn’s first breathings in the heav’ns above”—which breaks through the black darkness of the Active and the Passive Nights; they would tell us, too, of the soul’s further progress towards the Sun’s full brightness. It is true, of course, that some part of this great gap is filled by St. John of the Cross himself in his other treatises, but it is small compensation for the incomplete state in which he left this edifice of such gigantic proportions that he should have given us other and smaller buildings of a somewhat similar kind. Admirable as are the Spiritual Canticle and the Living Flame of Love, they are not so completely knit into one whole as is this great double treatise. They lose both in flexibility and in substance through the closeness with which they follow the stanzas of which they are the exposition. In the Ascent and the Dark Night, on the other hand, we catch only the echoes of the poem, which are all but lost in the resonance of the philosopher’s voice and the eloquent tones of the preacher. Nor have the other treatises the learning and the authority of these. Nowhere else does the genius of St. John of the Cross for infusing philosophy into his mystical dissertations find such an outlet as here. Nowhere else, again, is he quite so appealingly human; for, though he is human even in his loftiest and sublimest passages, this intermingling of philosophy with mystical theology makes him seem particularly so. These treatises are a wonderful illustration of the theological truth that grace, far from destroying nature, ennobles and dignifies it, and of the agreement always found between the natural and the supernatural—between the principles of sound reason and the sublimest manifestations of Divine grace.
