During periods of aridity and excessive activity of the imagination the soul can turn to meditative reading. When the soul is unable to meditate it can turn to a book to help collect the wandering thoughts and bring its soul in touch with God. St. Teresa of Jesus confesses to not being able to meditate without a book for many years and recommends this practice.
The choice of book should be one that is devout and will help in time of prayer. The Gospels are always a good choice and are of great assistance in this matter. The book can also be one of the writings of the saints. It should be one that is practical and affective, not too speculative or intellectual. This is to foster love, a work of the heart, rather than that of the mind.
