A cornerstone book on mystical theology, Interior Castle describes the seven stages of union with God. Using everyday language to explain difficult theological concepts, Teresa of Avila compares the contemplative life to a castle with seven chambers. Tracing the passage of the soul through each successive chamber, she draws a powerful picture of the path toward spiritual perfection. It is the most sublime and mature of Teresa's works, offering profound and inspiring reflections on such subjects as self-knowledge, humility, detachment, and suffering.

One of the most celebrated works on mystical theology in existence, as timely today as when St. Teresa of Avila wrote it centuries ago, this is a treasury of unforgettable maxims on self-knowledge and fulfillment.
