On Prayer and The Contemplative Life

This book was the work of St. Thomas Aquinas, the great master of mystical theology in the 13th century. The book teaches the wisdom on prayer and contemplative life in the form of question-answer organized into the subjects of the virtue of religion, devotion, prayer, the prayers of the saints who are in heaven, contemplative life, active life, comparison between active life and contemplative life, and religious state. Each subject contains many related questions and each question is answered in great philosophical and theological depth, accompanied with different arguments and the thoughts from the great minds and spirits such as Cajetan and S. Augustine.
