Father Sergius by Leo Tolstoy

A proud young nobleman, shattered by a personal betrayal, renounces his rank and worldly life to become a monk and pursue extreme asceticism; celebrated as a holy man, he struggles with pride, sexual temptation, and the corrupting effect of public admiration, ultimately abandoning the monastery after a humiliating failure and finding a quieter, humbler form of spiritual honesty through solitary wandering and simple service.
