The Interior Castle by St. Teresa of Avila presents a remarkable description of the entire spiritual life from the first release from mortal sin into Sanctifying Grace through the Mystical Marriage of the soul with Christ as a journey through what she called The Interior Castle. She sees the soul as a magnificent castle full of spacious and well-lit rooms or mansions each of which leads deeper into the heart of the castle to the seat of the King. However, St. Teresa laments that most people give all their attention to the outer wall of the castle the body ignoring the beauty of the soul within. St. Teresa gives practical advice regarding the early struggles and the temptations to turn back which beset the beginner. She describes each of the seven mansions and urges us forward to love and serve the Divine Majesty, imparting her absolute conviction that progress toward God through prayer is worth vastly more than all the treasures of this earth.

The Way of Perfection (Spanish: Camino de Perfecci�n) is a method for making progress in the contemplative life written by St. Teresa of �vila for the members of the reformed monastery of the Order she had founded.Teresa called this a "living book" and in it set out to teach her nuns how to progress through prayer and Christian meditation. The first 18 of the 42 chapters discuss the rationale of being a Carmelite, the rest deal with purpose and approaches to spiritual life.Conceptions of Divine Love was written in 1577. St. Teresa wrote this with the idea of explaining certain words found in the Book of Canticles. When her confessor read the title of her work, he ordered her to immediately burn it, which, of course, she did. But one of her nuns had copied the first seven chapters, which was then published in 1612. Here, Father John Dalton has translated only four of those chapters in 1852.
