A Tour of the Interior Castle
Teresa of Avila: Interior Castle: Summary – Mansions One through Six.

Even those devoting much of their life to studying spiritual literature find the Interior Castle a complex book. Richard Foster, founder of Renovare and author of the classic spiritual formation book Celebration of Discipline said, “For some reason, Teresa of Avila has always been difficult for me to read.” (Devotional Classics. Edited by Richard J. Foster and James Bryant Smith. HarperOne.)

The late Dallas Willard was a professor at the University of Southern California’s School of Philosophy. He wrote a number of influential Christian books including The Divine Conspiracy, The Spirit of the Disciplines, and Hearing God. Willard said of the The Interior Castle, “It is not a model of easy reading . . . and must be approached as if you are mining for treasure–which you are.” (The Great Omission: Reclaiming Jesus’s Teachings On Discipleship. 2006. HarperCollins Publishers.)

To add to the intellectual challenges of the Interior Castle, I face cultural barriers. Teresa was single and lived in a convent in the 1500’s. I live in a modern context. I’m married with children and grandchildren. I work outside of the church. Teresa was Catholic and I’m not, so, I no doubt, miss some of the religious context assumed by Teresa.

But it’s worth mining for the treasure. Others have recognized this as well. The Interior Castle is on several lists of “great books”. It’s included in Notre Dame’s Great Books seminars. Eugene Peterson lists it as one the “basics” of spiritual reading in his book Take and Read. It’s also included in 25 Books Every Christian Should Read (Edited by Julia L. Roller). Teresa provides an immense amount spiritual insight in the Interior Castle. Studying this book will certainly be rewarded, but also possible to get lost in the vastness of her ideas. To help keep track of her ideas I like to keep an outline/summary of The Interior Castle. I’ve added hyperlinks so you can easily find more detail on something that catches your attention.

A Tour of the Interior Castle

The Interior Castle is our soul. According to Teresa of Avila, our soul is like a single diamond in which there are many rooms. At the center of the Castle is where the King (Jesus) resides. The soul has great dignity and beauty and is a paradise in which God takes great delight. Teresa asks, “what do you think a room will be like that is the delight of a King so mighty, so wise, so pure and so full of all that is good?”  

We enter the Interior Castle by prayer and meditation. Our destination is the center of the castle where the most “secret things pass between God and the soul”. This is the interior journey. Teresa says, “You will have read certain books on prayer which advise the soul to enter within itself: and that is exactly what this means.”

The Foundation

  • The Interior Castle: This is Teresa’s metaphor to understand our souls. She describes our soul as a castle made of a single diamond in which there are many rooms. Christ dwells at the center of this castle.
  • The Image of God: Being created in the image of God is our core identity. Teresa says, being “made in His image means that we can hardly form any conception of the soul’s great dignity and beauty.” We hold this to be true while at the same time accepting the great distinction between creature and Creator.
  • The Indwelling Trinity: The indwelling Trinity validates the beauty and dignity of our souls and the importance of the interior journey. At the center of the castle is where the most intimate exchanges take place between God and the soul.
  • The Beauty and Dignity of our SoulsTeresa says, “I can find nothing with which to compare the great beauty of a soul and its great capacity.”

The Basics

  • Self-Knowledge: Teresa says we should learn self-knowledge and humility. It is important to understand who we are and the capacity of our souls for God. Progress through the Interior Castle requires even the most spiritually mature to spend time in the rooms of self-knowledge.
  • Spiritual Favors: Spiritual favors shatter complacency and fuels spiritual growth. Properly applied, they lead to good works, humility, virtue, praise, love, and fortitude. With spiritual favors, the progress of our souls takes place with less effort. While spiritual favors are important and add substance to our spiritual lives, Teresa says, “perfection consists not in consolations (spiritual favors) but in the increase in love”. We do not earn these favors nor are they a measurement of our goodness.
  • Prayer and Meditation: Prayer and meditation are the entry point to the Interior Castle. While we do not earn God’s favors, we can be more attentive to him. As we go into other rooms of the castle we may practice ascetic prayer and experience mystical prayer. Ascetic prayer is action we initiate with God. Mystical Prayer is action God initiates with us.
  • Reptiles: Reptiles are preoccupations or “worldly attachments”. They keep us anchored in the courtyard inhibiting us from exploring the rooms of the castle.
  • Sin: We are a Tree of Life. When planted in the “living waters of life” we thrive spiritually and bring renewal to a battered world. When we plant ourselves in or by the polluted waters of sin we limit our spiritual progress and miss opportunities to give life to others.
  • Spiritual Warfare: Three strategies in which the Devil excels are: (1) Getting us to believe lies – especially about ourselves (2) Distracting us from what is important and (3) Undermining love.

Additional Tools to Help Us Navigate the Interior Castle

  • Listen to God: He speaks to us through conversations with good people, sermons, books, trials, and prayer.
  • Develop Spiritual Habits: Establish sustainable “spiritual habits” especially around prayer and meditation. Start Small, Repeat Daily.
  • Rely on Your Faculties: Your reason, faith, memory, will, and understanding are reliable guides. Use them.
  • Perseverance: We drive the devil away when we resolve not to be defeated.
  • Increase Velocity: Teresa says we must avoid “this habit of always serving God at a snail’s pace!” and spending our time refining “our carefully ordered life”.
  • Avoid Distractions: We cannot live virtuous lives and still cling to wealth or reputation. Distractions will keep us from surrendering all to follow Jesus.
  • Find a Spiritual Director: When I talk about spiritual directors, I’m talking about wise people with a holistic approach to life and spirituality.
The Interior Journey 

The Interior Castle is about Prayer. Prayer can be separated into two categories:

  1. Ascetic Prayer: In ascetic prayer we initiate interaction with God through vocal prayer and meditation. This is also called “purgative prayer” because of the cleansing effect on our lives. The first three Mansions of the Interior Castle cover this material.
  2. Mystical Prayer: God drives the activity in mystical prayer. Teresa writes about this in Mansions four through seven.

We can then separate mystical prayer into two categories:

  • Illuminative Prayer: Through illuminative prayer God enlightens our will and understanding. Teresa explains this in the Fourth Mansions. This section includes several posts on the Prayer of Quiet.
  • Unitive Prayer: In Mansions five through seven Teresa writes about unitive prayer. Unitive prayer leads us to a deep and intimate relationship with Christ “where the most secret things pass between God and the soul.” Unitive prayer covers 2/3 of the Interior Castle and is the focal point of the book.

Unitive Prayer: When we explore Mansions Five, Six, and Seven the marriage metaphor becomes essential for our understanding of the Interior Castle. This metaphor is common in the Bible and other spiritual writings. The marriage metaphor helps us better understand the potential intimacy we can have with God. Teresa reminds us that this metaphor has limitations and is completely spiritual: “The spiritual joys and consolations given by the Lord are a thousand leagues removed from those experienced in marriage.” 

Teresa explains Unitive Prayer using the marriage customs of her day. This includes:

  1. Brief Meetings: A brief time in which we see our future Spouse. (Fifth Mansion)
  2. Betrothal Period: The promise to marry and learning to love Christ. (Sixth Mansion)
  3. Marriage: Union with Christ. (Seventh Mansion)

The Sixth Mansions of the Interior Castle

In the Sixth Mansions, we are at a critical juncture in our Christian life. The potential for deep spiritual union with Christ is within reach. But the devil wants to prevent this union. He wars against us. And this time he makes the poison seem so harmless. Some of us have gotten close to the Sixth Mansions and been tricked. Additionally the Sixth Mansions comes with Intellectual Visions, Imaginative Visions, periods of Ecstasy, and intense suffering.

The Seventh Mansions
Teresa begins the Seventh and final Mansions by saying, “You will think, Sisters, that since so much has been said about this spiritual path it will be impossible for anything more to be said.” After three years of blogging and 220 posts, I can feel that way once in awhile. But then Teresa reminds me, “Such a thought would be very foolish. Since the greatness of God is without limits, his works are too.” The discoveries we make in getting to know Christ on this interior journey are infinite and inexhaustible. As we move into the Seventh Mansions of the Interior Castle we will discover the deepest levels of intimacy with Christ.

Thanks for reading Teresa of Avila Turns 500.

    This is such an excellent summary… Thorough but at the same time very straight forward and clear… I enjoyed the excerpts regarding The so called Tour of the Interior Castle and also that one related to the additional `required´to´Navigate the Interior Castle…
    I have the impression that the book is mostly metaphorical… Which is something interesting as symbolic language is always open to interpretations and might be applied to different scopes of Life… and not exclusively religion… Correct me if I am wrong … But I hint that one could read this colossal book from different perspectives…
    Thanks for sharing, dear Dave. All the best to you!, Aquileana 😀

    • Dave Small says:

      Aquileana, Thanks for reading and sharing your insightful comments. You’re right the book is filled with metaphors – in fact, the “Interior Castle” itself is the main metaphor followed by many, many others. You mentioned applying the metaphors outside the scope of religion — Teresa’s metaphors are so good I find myself applying them to multiple situations and they work well. Have a great week Aquileana.


  2. Resa says:

    Dave, Aquileana has said what I’m thinking, only she has articulated it better than I can. The main thing here for me is the ability to approach the metaphor from whatever perspective I choose, or need. I have always thought that the concept of the “Castle” is intriguing.
