The Fiery Dart of Divine Longing — The Interior Castle

Teresa warns that sublime favors do not settle the soul; the little butterfly still sighs because each grace increases longing and knowledge of how God deserves love. Yearning that once felt like a smouldering fire becomes unbearable when a passing thought of delayed death strikes the heart like a fiery dart wounding the centre of the soul. Reason and will cannot resist; faculties are fettered except to intensify torture, and cries escape even the patient. Teresa compares this to purgatory and notes physical peril: joints dislocate, pulse weakens, health may remain enfeebled for days afterward.

The soul hangs suspended, thirsty for God alone, lonely among creatures and even saints because they are not her Beloved. Though she has surrendered to God's will, she cannot conform now; this is irresistible suffering like fire that must burn whoever is thrown into it. Hell lacks the resignation and profit of such pain; Teresa urges gratitude for a state where mercy may free us.

The dart passes in hours, leaves contempt for the world, deeper detachment, and fear of offending God who can torment and comfort. Two dangers threaten life: this agony and excessive spiritual joy. Courage is required; Christ asks the sons of Zebedee whether they can drink His chalice, and Teresa believes we should answer yes, trusting strength when needed.
