The dark night of the soul is a phrase from the 16th century Spanish mystic John of the Cross. It describes a period of spiritual emptiness, doubt, and loss of meaning that some people pass through on the way to deeper faith or insight. Today it is often used for any painful season that leads to inner change.
Why It Matters
Knowing this season has a name can bring relief. Many traditions treat it as a passage, not a failure, and encourage patience and support.
