As a monk, in disobedience to his superior, Nicetas left the monastery and closed himself in a cell. Because of his disobedience, God permitted great temptations to befall him. Once, when Nicetas was at prayer, the devil appeared to him undeer the guise of a radiant angel and said to him: "Do not pray anymore, but rather read books and I will pray for you!" Nicetas obeyed, ceased to pray, and began to read books.
