Teresa's masterwork of contemplative theology, describing the soul as a crystal castle with seven dwelling places through which one travels toward union with God.
The Interior Castle is a central text in the Christian mystical tradition, offering insight into the spiritual life, the nature of divine union, and the transformation of the soul.
The soul is like a castle made entirely of diamond or of very clear crystal.
In this castle there are many rooms, just as in heaven there are many mansions.
The door to enter this castle is prayer and reflection.
