John of the Cross was a small man of immense interior intensity. Born in Castile to a poor family, he became a Carmelite friar in his teens, met Teresa of Avila in his twenties, and joined her in the project of reforming the Carmelite order along strictly contemplative lines. The reform brought conflict. In 1577 his Carmelite opponents kidnapped him and held him for nine months in a tiny cell in Toledo, where he was beaten weekly and given barely enough to live on. It was in this cell that he wrote the verses of the Spiritual Canticle.
His four major works, all written after his escape, form a single integrated map of the contemplative path: the Ascent of Mount Carmel, the Dark Night of the Soul, the Spiritual Canticle, and the Living Flame of Love. The Ascent and the Dark Night describe the systematic stripping required for union with God: first the senses, then the affections, then the most subtle attachments of the spirit itself. Each layer of identification has to fall.
The phrase dark night of the soul has entered the language but is usually misunderstood. John does not mean depression or grief. He means the technical contemplative event in which God removes from the soul every consolation, every felt presence, every spiritual support, including faith and hope as feelings, leaving the soul in apparent abandonment. This darkness is not absence but presence: God is closer than ever, but in a mode the soul cannot register. The soul is being purified of its dependence on its own experience.
His prose is austere and precise. His poetry, written in the same period, is among the greatest in Spanish literature. He died at forty-nine, exhausted by reform politics and asceticism. He is read across the Christian contemplative tradition and far beyond it, by Buddhists, Sufis, and Advaitins who recognise in his maps of the path their own.
