The Dark Night: What John of the Cross Meant

A dark night of the soul, in the man who coined it, is not a bad year. It is not grief, burnout, or a depressive episode. It is a specific and fairly narrow condition: prayer that used to bring warmth goes flat, and nothing else fills the gap either. The person keeps going. That is the whole point of it.

Juan de Yepes was born at Fontiveros in 1542 and died at Ubeda in 1591, forty-nine years old. He was a Carmelite friar, and the trouble that produced the phrase came from inside his own order. In December 1577 friars opposed to the reform he worked on with Teresa of Avila took him by force to Toledo and shut him in a cell roughly six feet by ten. He was there about nine months, beaten weekly, on bread and water and scraps. He escaped in August 1578 by loosening the hinges of his door and climbing down a wall on a rope of cut blankets.

He was canonised in 1726 and named a Doctor of the Church in 1926. The English phrase reached self-help through translations of his commentary, and along the way it stopped meaning purification and started meaning any prolonged bad patch.

Before the treatises there is a poem. Eight stanzas of five lines each, in the Italian form Spanish poets called the lira, opening on the line every anthology prints: En una noche oscura. On a dark night.

Read cold, with no theology attached, it describes a woman slipping out of a sleeping house to meet her lover, guided by nothing but the fire burning in her chest, and the darkness is her ally because it hides her. Nobody is suffering in this poem. The night is the good part.

That is worth sitting with, because it inverts the modern usage completely. In the poem the dark is a cover that lets the meeting happen. The pain in the later prose comes from the person's habits being taken away, not from the dark itself.

John wrote two prose works explaining that single poem, and left both unfinished. The Ascent of Mount Carmel, composed roughly between 1581 and 1585, and the Dark Night, from around 1584 to 1586. They cover the same ground from two directions: the Ascent describes what the person does, the Dark Night describes what is done to them.

Neither reaches the end of the poem. The Ascent stops partway through its third book. This matters for anyone quoting them, because a good deal of what people attribute to John about the later stages simply is not in the text he left.

The structure is a grid, and English summaries almost always flatten it. Two zones, two modes.

The zones are sense and spirit. The night of sense strips the appetite for consolation, the pleasure taken in devotion, images, feelings, results. The night of spirit goes further in and works on the understanding, the memory and the will.

The modes are active and passive. Active means the person does it: chosen restraint, chosen simplicity. Passive means it happens to them and no technique brings it on or ends it. Almost every practice book on the market is describing the active night of sense and calling it the dark night of the soul. Those are two different rooms in the same house, and the far one is not reachable on purpose.

This is the part worth having. John knew people would confuse the purgative dryness with laziness, sin, or being unwell, so in the first book of the Dark Night he gives three tests, and says all three must be present together.

First: the person finds no pleasure or consolation in the things of God, and also fails to find it in anything created. If the appetite has simply moved to something else, food, distraction, a new enthusiasm, this is not it.

Second: the memory is ordinarily centred upon God, with painful care and solicitude. The person is anxious about not serving well, and thinks they are going backwards. Indifference points the other way, to what he calls lukewarmness.

Third: the person can no longer meditate or reflect in the imaginative sphere of sense as they were accustomed to. The old method of working through a scene in the mind stops functioning. John adds the check that matters clinically: if this comes from indisposition, then when the indisposition ends the ability comes back. He also notes the state can be increased by melancholy or some other humour, which in his vocabulary is a bodily condition, not a spiritual one.

Three signs, all three at once, and one of them is explicitly a rule for excluding illness.

John built an exclusion test into his own scheme, so it is fair to apply it. Persistent low mood, loss of interest in everything including the things that used to work, disturbed sleep and appetite, thoughts of self-harm: that is a clinical picture and it belongs with a doctor, not with a sixteenth-century Carmelite. His second sign in fact points away from depression, since it requires an active, aching attention that depression tends to flatten.

Calling a depressive episode a dark night of the soul sounds dignifying. In practice it delays treatment, and John himself would not have made the mistake, because he wrote the third sign specifically to catch it.

Start with the poem, in Spanish alongside a translation if you can, and read it as poetry before anyone tells you what it means. Twenty lines of prose commentary will not give you what those eight stanzas do.

Then read the first book of the Dark Night, chapters eight to fourteen, and skip the rest until you want it. That is where the three signs and the diagnostics live, and it is short.

What survives translation into any practice, religious or not, is one instruction: when the method stops working, do not reach for a better method. John's whole argument is that the ability to meditate is withdrawn on purpose, and that the correct response is to stop trying to restart it. That advice is unusual enough to be useful, and it is 440 years old.
