In this penetrating guide to the interior life, Fr. Basil W. Maturin explains why sincere efforts to follow Christ can falter and how authentic self mastery is attained through disciplined cooperation with grace. He explores the nature of temptation, the training of the will, and the importance of true self knowledge, distinguishing genuine self denial from unhealthy rigor. With practical counsel on governing thoughts, purifying motives, and cultivating ordered love, this book offers a steady path toward deeper freedom, balance of soul, and lasting growth in holiness.
