Key Quotes
"I thought of the soul as resembling a castle, formed of a single diamond or a very transparent crystal, and containing many rooms"
"It seems to me that many souls are like this: they live in the courtyard of the castle and never think of entering it"
"No night can be so dark, no gloom nor blackness can compare to its obscurity"
"They resemble persons in a dark dungeon, bound hand and foot, who can neither move nor see nor feel the warmth of the sun"
"Blessed is the man that feareth the Lord"
"Unless they turn back in their course they are on the safe road to salvation"
"It would seem that they must have gained the mastery over this world, or at least be extremely detached from it, yet if His Majesty sends very moderate trials they become so disturbed and disheartened as not only to astonish but to make me anxious about them."
"Having practised virtue for so long they think themselves capable of teaching it, and believe that their sufferings are endured for God's sake."
"Henceforth they begin to be supernatural and it will be most difficult to speak clearly about them, unless His Majesty undertakes it for me"
"Let the mill clatter on and let us continue to grind our wheat"
"I forget what I was speaking about, for my occupations and ill-health often force me to cease writing until some more suitable time."
"What I call divine consolations... begin in God and end in ourselves, being felt in a very different manner."
Discussion Questions
1. Teresa says most people live like strangers in their own homes, knowing they have souls but never exploring them. What does she mean by this, and how does she suggest we start exploring our inner 'castle'?
From Chapter 1 →2. Why does Teresa compare souls without prayer to paralyzed bodies? What's the connection between self-reflection and being able to 'move' through life effectively?
From Chapter 1 →3. What does Teresa mean when she describes souls in mortal sin as trees planted beside poisonous waters?
From Chapter 2 →4. Why does Teresa say the devil works hardest against beginners in their spiritual journey?
From Chapter 2 →5. What does Teresa mean when she says Third Mansion souls are like the rich young man who walked away from Jesus?
From Chapter 3 →6. Why do people who pray regularly and avoid major sins still experience spiritual dryness and dissatisfaction?
From Chapter 3 →7. Teresa describes people who appear virtuous but fall apart during small setbacks. What specific examples does she give of how these souls react to minor trials?
From Chapter 4 →8. Why does Teresa say that God allows these small trials to happen? What do these tests reveal that years of prayer and good works might not show?
From Chapter 4 →9. What's the difference Teresa describes between the sweetness we create through our own efforts and true spiritual consolations?
From Chapter 5 →10. Why does Teresa say we suffer unnecessarily when our minds wander during prayer or focused activities?
From Chapter 5 →11. Teresa describes two different fountains - one that needs pipes and machinery, and one that fills directly from the source. What's the difference between these two ways of finding peace or fulfillment?
From Chapter 6 →12. Why does Teresa say that the more we chase extraordinary experiences or peak moments, the more they seem to slip away from us?
From Chapter 6 →13. How does Teresa describe the difference between regular prayer (where we do the work) and the prayer of recollection (where God initiates)?
From Chapter 7 →14. Why does Teresa warn against trying to force spiritual experiences through extreme practices or artificial mind-emptying?
From Chapter 7 →15. Teresa describes the 'prayer of union' as being like falling into a divine coma where you can't think or move, yet you're more alive than ever. What makes this different from just daydreaming or falling asleep?
