by St. Teresa of Avila (1577)
I would not recommend reading this book — even a study edition — without first having been prepped by Fr. Thomas Dubay’s Fire Within. If you are wrestling with trying to locate yourself within the landscape of the spiritual journey, Teresa of Avila will help shed some light, but I will warn that reading her raised as many questions as answers for me. This is not all bad: we are talking about an extremely transcendent subject, so anything less would not be nearly as interesting, and even captivating and engrossing.
Her basic model is of a castle with seven chambers, each of which represents a major stage within the soul’s spiritual journey inward. The first three are fairly basic, but the fourth is clearly a departure, in which the beginnings of contemplative prayer are discovered. Five, and especially six and seven, are described in ways that are full of vivid imagery and indications of exceptional phenomena, though I have come to understand that these are not necessarily essential.
If you are going to explore deeply the mystical aspects of the spiritual life, you will not want to omit St. Teresa. Just go in prepared.
