Reverend Paisius wanted to publish a book useful to everyone: laity, monks and clergy, but he did not have time, devoting all his time and energy to prayer and communication with people who came to him. After the saint’s repose, his letters, recordings of teachings and conversations were systematized for ease of use in everyday life, for the elder himself said: “The task is for you to work and apply what you hear in practice.” The third volume of “Words” by St. Paisius the Holy Mountain is a guide to the sea of spiritual life. People suffer from anxiety, insomnia, and mental illness, and the reason for this is their vain, corrupted, false thoughts that they trust. The monk teaches how to practice good thoughts in various life situations, benefiting from everything.
