What Is the Dark Night of the Soul?

The phrase gets used loosely now — any rough patch, any stretch of feeling lost. But it began as a precise term for a specific and strange experience: a period on the spiritual path when everything that once felt warm and alive goes cold, when God or meaning seems suddenly absent, and the practices that used to console you turn to ash in your hands. What makes it remarkable is that the people who described it most carefully insisted it was not a failure or a breakdown — but a passage, a stripping-away that precedes a deepening. And the same passage shows up, named differently, across traditions that never spoke to one another.

What St. John of the Cross actually meant

The term comes from a 16th-century Spanish Carmelite friar and mystic, St. John of the Cross, who wrote a poem and commentary called La noche oscura del alma — “the dark night of the soul.” He was not describing depression or a crisis of faith. He was describing a stage of spiritual purification.

In his account, the soul that has made real progress is led into a darkness in which God deliberately withdraws the felt rewards of devotion. Prayer goes dry. The sense of God’s presence — the very thing the seeker built their life around — disappears. John’s startling claim is that this absence is itself the work of grace: the soul is being weaned off its attachment to experiences of God so that it can be united with God directly, beyond feeling. The darkness, in other words, is not God leaving. It is God working below the level where the self can take comfort or credit. It is painful precisely because it is profound.

The same passage across traditions

What’s striking — and why this belongs on a map of patterns rather than a single tradition — is how many contemplative paths describe the same desolation as a marker of depth, not a sign of failure.

• Early Christian monasticism had a name for the closely related affliction centuries before John: acedia, the “noonday demon” of the desert fathers — a spiritual listlessness and despair that the monks treated not as a moral lapse but as an expected trial of the contemplative life.
• Buddhism maps something remarkably parallel in advanced meditation: the so-called “dark night” or dukkha ñanas — the difficult “knowledges of suffering,” stages of insight in which the practitioner is confronted with the unsatisfactoriness and dissolution of experience, often as a wall of fear, misery, and disgust before a breakthrough to equanimity. Modern teachers borrowed John’s exact phrase because the territory matched.
• Sufism speaks of the seasons of spiritual contraction (qabd) and the ache of separation from the Beloved that drives the soul onward — the longing in Rumi is the dark night turned into poetry.
• Even the Gospel places the experience at its center: Christ on the cross cries “My God, my God, why hast thou forsaken me?” (Matthew 27:46) — the felt absence of God at the very moment of greatest spiritual significance.

And in the modern era the most famous case is Mother Teresa, whose private letters revealed that for roughly the last fifty years of her life she experienced a near-total absence of the felt presence of God — and continued her work anyway. Her spiritual directors read it, explicitly, as a dark night: not a loss of faith, but faith stripped down to bare will. The convergence is the point. Independent traditions keep reporting that the path passes through a desert, and that the desert is on the way in, not out.

Dark night, depression, or existential crisis?

This distinction matters more than any other on this page, so it gets said plainly — and with a caution.

A dark night, as the mystics describe it, is a spiritual desolation in which the longing and the sense of meaning remain intact: the seeker still wants God, still values the path, still feels the absence as an absence of something real and loved. It typically comes after genuine spiritual depth, not instead of it.

Clinical depression is different, and the two can co-occur. Depression tends to flatten desire and meaning altogether — not “God feels absent” but “nothing matters and I don’t even miss it” — and it carries physical and cognitive symptoms (sleep, appetite, energy, hopelessness, thoughts of self-harm) that are medical, not mystical. If that’s where you are, please treat it as health, not theology: talk to a doctor or therapist, and if you’re in crisis, reach out now — in the US and Canada you can call or text 988, or find an international line at findahelpline.com. No spiritual framing should ever stand between you and help. The dark night is real, but it is not a reason to suffer a treatable illness alone.

And it differs again from an existential crisis, which is the collapse of secular meaning — the felt absence not of God but of any point at all. The three can overlap, but they’re not the same terrain, and naming which one you’re in is the first step toward what helps. (If what you feel is more like numbness than darkness, why do I feel empty? may fit closer.)

What we actually know

What can be said plainly: the dark night of the soul is a recognized and well-documented stage of the contemplative life, not a modern metaphor — and not, by itself, a synonym for depression. Across traditions that developed in isolation, serious practitioners kept reporting the same structure: a desolation, a felt withdrawal of the divine, a stripping-away of consolation, arriving after real depth and standing before a further deepening. St. John, the desert fathers, the Buddhist insight maps, the Sufis, Mother Teresa — different cosmologies, the same dark passage.

That pattern can’t be proven to mean what the mystics say it means. But it tells you something useful even if you grant it nothing metaphysical: the people who have gone furthest on these paths expected the darkness, named it, and did not read it as evidence they’d failed. If you find yourself there — and it is genuinely a dark night and not an untreated illness — you are, at minimum, in very experienced company, and they are nearly unanimous that it is not the end of the road.

Frequently asked questions

What is the dark night of the soul? A term coined by St. John of the Cross for a stage of spiritual purification in which God’s felt presence withdraws and devotion goes dry — described not as failure but as a deepening that works below the level of feeling. Parallel experiences appear across traditions. What is ego death? →

Is the dark night of the soul the same as depression? No, though they can co-occur. A dark night keeps longing and meaning intact (you still want God and feel the absence as loss); depression tends to flatten desire and meaning entirely and carries medical symptoms. If you may be depressed, treat it as health and seek help. Why do I feel empty? →

How long does a dark night of the soul last? There’s no fixed length — the mystics describe anything from a season to years. Mother Teresa’s, by her own letters, lasted roughly fifty years. The tradition treats duration as less important than not mistaking it for failure or for a treatable illness. What is an existential crisis? →

Do other religions describe the dark night of the soul? Yes — strikingly so. The desert fathers called the related affliction acedia; Buddhism maps the “dark night” stages of insight (dukkha ñanas); Sufism describes spiritual contraction and the ache of separation; and the Gospel places “why hast thou forsaken me?” at its center. Are all religions the same? →
