Life and asceticism
According to the tradition preserved by Theodoret of Cyrrhus, Mausimas was of ordinary, rustic origins and was Syrian-speaking. Although he lacked formal education, he was remembered for the strictness and simplicity of his manner of life. His asceticism was unpretentious rather than dramatic: he is said to have worn the same tunic and goat's-hair cloak for a very long time, sewing fresh rags over the tears as they appeared rather than replacing the garments.
He made his dwelling a place of open hospitality, throwing open its doors to all who came and giving particular attention to the care of strangers and the poor. The Orthodox synaxarion summarizes his vocation as the voluntary embrace of poverty for the sake of serving his neighbor.
